(This is a reader gun review contest entry, click here for more details – enter by December 26th!)

By Travis Pike

A long time ago I was a young, naive kid, looking to serve my country. I chose the Marine Corps and was hell bent on the infantry. So in my recruiter’s office staring my future down, I knew I wanted to be a machine gunner. The Marine Corps splits the infantry into different jobs and machine gunner is a real MOS (0331). I also had an interest in firearms and I liked shooting guns that went bang, so why wouldn’t I want to shoot one that goes bang, bang, bang, bang really fast? . . .

The M240 is not an attractive weapon, but the first time you fire it is something you’ll never forget. In my five years FN’s M240 and I became close friends. The M240, in case you don’t know, is a 7.62 NATO gas operated, open bolt, air cooled, crew served, fully automatic machine gun. The 240 is the Marine Corps’ standard for medium machine guns.


The M240 is an absolute beast. The first time I got my 240 it was in a heavy canvas bag, taken apart, shoved in there with two barrels, a T&E, and a tri pod. The weapon is outfitted with an optic rail on the top cover and two short rails on either side of the barrel. It’s an awkward looking beast, completely lacking the streamlined appearance of classics like the MG 42. It’s heavy, too…about 27 pounds and is most comfortably carried on the shoulders. Ergo, it pretty much suck when it comes to carrying the weapon.

Crossing river


The 240 uses a simple push button safety positioned awkwardly behind the trigger. The grip is huge, by the way. For guys like me who have big hands it’s okay. Small guys may have trouble, though. The charging handle is non-reciprocating, and locks when in the forward position. Reloading is simple; open the tray, sweep any links, line up a new belt, close the lid, rack the charging handle, place on safe. I could go on about changing the barrel, but I doubt anyone really cares.

The trigger is like a sponge. It’s bad and it’s a bit long, and stupid-spongy. Once that trigger is pulled though, hold on. The M240’s weight soaks up most of the recoil, but without some training and experience you aren’t going to be very effective at hitting much beyond a hundred yards.

Speaking of range and accuracy, the M240 is a superbly accurate gun. With the 240 you aren’t aiming to make a small group, but to suppress and destroy stuff. For example, at a thousand yards we could walk our guns onto a car carcass and hit it all day long. The sound of metal on metal was enough to let us know we were ponyboy golden. We could even knock down man-sized Ivan targets out to 800 yards pretty easily with someone spotting. Remember, this is using iron sights, but we did have a tripod so maybe I’m being a little self flattering.

Reliability? Don’t even get me started. The gun doesn’t stop. Sandstorm in UAE during a force-on-force training op? The 240s are the only guns that are still working. Get it wet? No problem. Shoot a few thousand rounds and not clean it? Go ahead. Wanna run blanks through it for a week? Go ahead. It just keeps going. Run out of lube? Spit, piss, or bleed in it, work the bolt and it will keep going.

Best way to clean it? With a pressure washer. On one field op we were on the last day and the good idea fairy decided to provide us with another 10,000 rounds. We took two guns, and let ‘em rip. We dumped CLP in the actions every thousand rounds and kept going. It was raining, but the barrels were still hot enough to light cigarettes off of.

So disassembly is a snap and can be done quite quickly, but I doubt anyone wants me to walk them through it. It isn’t as simple as twisting a pin and removing it. Rather it’s a multi step process with a few pins, springs and pieces.

What makes the M240 such a kick ass weapon is the fact it stops fights pretty quickly. Like Rosie O’Donnell at a buffet quickly. Machine guns will shut up enemy fire and take the will to fight out of any asshole that is dumb enough to pick a fight with a dude carrying one.


Firing a machine gun is an art. It’s not just pointing and spraying ammo down range and hoping something falls down. When machine guns work in teams and practice talking guns, it takes both machine gun teams to create an effective rhythm. A good machine gun squad (two teams) isn’t just shooting machine guns, they are make music. The tempo and rate of fire increases or decreases with our squad leader/composer to fulfill whatever our suppression goal is. It’s a symphony of ass kicking.

A machine gun should rarely be in action by itself, but it happens. A machine gunner still exercises fire discipline lest he blow his load and overheat his barrel. Unless you want to dump your ammo to make the patrol a bit easier.

I served five years with or around a M240 and I grew to love the beast. After carrying that pain in the ass you’d think I’d hate it, but even now all my memories of that gun are fond ones. In fact if I had to choose one gun as my favorite it would be the old faithful M240.


Model: FN M240
Caliber: 7.62 NATO
Magazine Capacity: As long as you want the belt
Weight Empty: Freakin’ heavy (27.1 lbs)
Barrel Length: 24.8 inches
Overall Length: 49.7 inches
Sights: Peep
Action: Open Bolt
Finish: Blued/Parkerized/ IDK
Price: Four years military service cause the NFA is totally lame

Ratings (out of five stars):

Style: * * 1/2
Pretty ugly, it’s awkward looking from the barrel-mounted handle to the weird pistol grip. The weapon is like a prized pig — it may be the greatest pig around, but it’s still a pig. The 2.5 stars are solely because it’s belt fed and belt fed weapons are a style class all their own.

Ergonomics – Carry: *
HAHAHAHAHAHAAHAHA! It’s heavy, unbalanced and awkward. The closest thing to comfortable carry is tossing it on your shoulder and letting those little metal pieces dig in nice and deep.

Ergonomics – Firing: * * * *
A very comfortable weapon to fire. The broad butt plate gives you a good shoulder and cheek weld. The bipod is strong and once it’s down, it’s not moving. The weight absorbs the recoil, and the user hardly feel anything. The awkwardly placed safety is, well, awkward. In terms of the fun factor, it was a belt-fed machine gun I got to shoot at people. Of course it’s fun.

Reliability: * * * * *
This thing steps up there with the AK in the gun reliability hall of fame. Maybe it’s because of the open bolt, or maybe it’s because of the fine craftsmanship FN places in their weapons. I don’t know. I’m a self-proclaimed internet gun expert, not a real one. Either way it grinds and works no matter the weather, environment, or amount of use.

Accuracy: * * * * *
From a prone position with a tripod, an experienced machine gunner can engage targets at over a thousand meters with a good A-gunner, tracers (they burn out before a 1,000 meters, though) and some right, tight and down-on-the-gun. On bipods, accurate engagement to six hundred meters on man-sized targets is pretty standard.

Customize This: * * *
The weapon can be outfitted with a variety of optics including night vision and thermal (although they suck after the barrel heats up), and optics like the MDO by Trijicon. The side rails allows the mounting of PEQ 15/16 laser devices. The new M240L introduced a shorter barrel and collapsible buttstock. New bipods have been introduced that are a bit lighter with spikes in the feet. Also, the weapon can be fitted with a soft belt container called a nut sack for starter belts on foot patrols.

Overall: * * * * 1/2
I want to give it a five stars, I really do. The main detractor is the weight, and awkward-to-carry nature of the weapon. Marines make due though. Plus the style is absolutely atrocious. The weapon works though. It is a fight stopper and game changer. The 240’s reputation among the troops is absolutely fantastic with a 100% confidence rating from soldiers in a study by Natick Soldier Center.

  1. The FN MAG is a pretty sexy beast. You’d give it more style points if the US Military hadn’t upped the weight with questionably useful heat shields and ruined the aesthetics along the way.

  2. @Travis Pike, awesome! Much better than the 60. Makes one wonder about the crybabies that piss and moan about a 7lb AR or a 9lb MBR.

    • M60 is far superior to the M240B. I have fired both. The M240 is more accurate than the M60 and that is it’s only advantage. The M60 is lighter and can be fired while standing or moving. The M240B requires the shooter to be prone or the gun to be mounted.

        • Same- Then again, the ones I had when I was in the National Guard were older than I was. I just remember using it more as a bolt action than an MG…

        • I completely agree that the M60 did not have stellar reliability. Feed trays wore out too quickly and the gas cylinder needed fairly frequent cleaning. It may be that our M60’s had been heavily used, but I’d rather have had a more reliable gun. I should say that I used one quite heavily, but never on the ground, always from a Huey. And my greatest horror in RVN, especially during LS 719, was that we were not given the opportunity to test-fire our weapons after major cleaning. Just flew right into battle/hot LZ’s hoping everything was good.

        • Never fired either, but I recall some years back the M60 was upgraded somehow specifically to address reliability problems, maybe the differences in experience is due to the dates people are referring to.

        • I carried an M60 a lot. If it jams its either REALLY neglected or worn out OR has new parts that may need a little shooting. I was in a Mech infantry company in VN and we shot a LOT. No significant complaints. But EVERYTHING has a failure rate. You have to remember that it replaced the Browning. Which was nearly flawless but old school. The 1917 water cooled Browning shot a 20000 round burst, yeah 2000 rounds, in testing. The army told JM Browning that they wanted the test repeated with a production gun. He came back with one and shot another 20000 round burst. The design was accepted.

      • Though yes the 60 is lighter you can indeed fire the 240 from the hip. In my unit we often mounted a grip on the left hand side of the gun for this exact purpose.

        • While you could fire the M60 “from the hip”, that’s just to suppress an unseen enemy where their basic direction is guessed; oh and in every hack movie/tv script and video game because it’s cool looking.
          If you know where you’re shooting, you fire the M60 from the shoulder. And that’s with the full weight version, not the stripped down SOCOM crap.
          Only issue we ever had was poor maintenance on one and worn parts on another (the rest were stellar), and both those issues went away when our unit got an actual armorer, and our First Sergeant started making the lazy operators do remedial PT after everyone went home for the day. And that was the early to mid 1990s.

      • We had a couple of man-beasts who could fire it from the shoulder.

        I could do that with the SAW, but not the 240.

      • You clearly never served in the military. Firing a couple of belts from a perfectly clean, meticulously maintained range toy at a gun club does not make you an expert on machine guns.

        The M60 was a fragile, unreliable, badly-designed piece of shit. There’s a reason that half the world adopted the FN MAG (M240) while the only countries besides the US that used the M60 were the ones who got free M60s as military aid paid for by US taxpayers.

        No Soldier or Marine who carried and used both in the field misses the M60. The M60 never should have been adopted. Even in 1957 the FN MAG was a more reliable and more durable GPMG. But narrow-minded fools demanded an “American” gun, even if it was nothing more than a lousy combination of a German designed bolt group and a German designed feed mechanism, fabricated out of flimsy inadequate steel stampings to save a few pennies.

        • This sounds like an idiot complaining about the M16, since it was made badly for a few months in 1968. While purposely ignoring the decades of superior performance after the initial issues were dealt with.
          Never explain to these morons just how awful the AK47 was in its first decade of existence, almost as if the SKS was kept in service in Bloc nations for a reason. Sure, by the late 1950s the Soviets finally got most of the kinks out, but Chinese AKs were total crap through the 60s and 70s (they also kept the SKS in use)…
          We loved our M60s, and would (for fun) strip then down to pieces and put them back together again in timed competitions, all while blindfolded.
          Only issues were if you failed to clean the thing, or your armorer was an idiot who refused to learn anything about the job (usually they weren’t actual armorers), including how to order new parts once and awhile.
          We were an actual Combat Arms Unit, we were expected to know how to use our gear, successfully and repeatedly, while in field.

    • Much better than a M60 is an understatement. When i was in the m240 was mounted coaxly with the man gun on my tank. The sheet metal and rivet beast would fire till the barrel glowed. the only problem we ever had was some run put to much lube on one and it ran off we had to break a link to get it to . It made me wonder why the service was so long in replacing the M60

  3. I wonder if it’s possible to get a semi auto version and fire it with an ATF approved hand crank?
    Wouldn’t be the same but if the trigger is nothing to brag about anyway, it would still be a close experience.

  4. Once again, a review of a weapon I’m not allowed to own. Is this supposed to make me jealous? Should I be prepared to rail against the ATF for closing the books on registering new machine guns? Because I will.

    • I’m no fan of the ATF, but your rage is misplaced. Congress closed the books on new machine guns in the 1986 FOPA bill. Blame William Hughes.

    • You can own these just fine. Just join that big hippie commune in the desert, they’ll practically make you shoot it on the finest two-way range since divorce court.

  5. I can’t believe people are rating machine guns by style – it’s a machine gun, not a Holland and Holland. If you think this is ugly, go look at a Potato Digger in action.

  6. If you put lipstick on it will it still be a pig?

    Some of the same complaints I had about my pig – M60. Old rock and roll.

  7. “The gun doesn’t stop. Sandstorm in UAE during a force-on-force training op? The 240s are the only guns that are still working. Get it wet? No problem. Shoot a few thousand rounds and not clean it? Go ahead. Wanna run blanks through it for a week? Go ahead. It just keeps going. Run out of lube? Spit, piss, or bleed in it, work the bolt and it will keep going.”

    Sounds like a Garand, only faster and a lot more lead downrange. Who said there is no “sporting purpose” to owning a machine gun?

    • You realize Garands had a lot of reliability problems right. They were better than most anything else around at the time, but there reliability was far overrated

      • Yeah it’s great rifle but everyone I’ve ever known that’s had one old or new has always had them f**k up and break. I think part of that has to do with the fact that you can’t shoot most modern 30-06 out of it because of the load changes, and most people don’t know that and just run any 30-06 they can find. Still, it’s enough to deter me from buying one if you can only run specialized ammo through it and even then chances are it’s going to jam and break.

      • “By most everything else” you specifically mean semi-auto rifles, right? I don’t think Garand was significantly more reliable (or more reliable in general) than any bolt-action service rifle of the time.

          • “I don’t think Garand was significantly more reliable (or more reliable in general) than any bolt-action service rifle of the time.”

        • The Garand would produce more hits per pound of ammo fired than the more accurate 1903, for example, in simulated combat. Donald Burgett, 101st Airborne, D-Day, Market Garden, Bastogne and into Germany would not use anything else. And when made squad leader he gave his Thompson to a replacement for the guys Garand. Stated what a HUGE advantage it gave over the K98. With the right ammo the in spec Garand is frighteningly reliable. In very cold weather, like Chosin, they had to be run dry but they still ran. A Medal of Honor winner at that fight was holed up with 3 wounded Marines and set his handguard on fire twice and had to put it out with snow, fought ALL night shooting Chinese at close range. Used at E-tool to scoup up chicom grenades and throw them back, his Garand never failed….. Watch newsreels of German infantry firing K98s in combat and then look to the Garand in use in combat footage. Its a no brainer….

      • You realize that the early problems with the Garand were related to a machine cut that was changed by someone other than Garand when full production started? It was human error and not a fault of the design as adopted.

  8. I got to fire one at the SF range in Iraq 9 years ago. Yep, ugly as hell but an absolute blast to shoot. Hardest part was ignoring my ingrained 3-round burst training. Just pull the trigger and let her rock and roll.

  9. Yes… the 240 how I love to hate thee. I’ve carried that metal monster on several humps and would prefer the SAW over that monstrosity. This is until you shoot it… then well yeah 240 all day. Great article, it gave me some flash backs of the field ops and the good idea fairy finding “fun” stuff for us to do during our down time.

  10. Not to be entirely too nit-picky, but why in an article about the M240B show a picture of the M60 and Marine carrying a M249 in the photo?

    I would also add the deterrent factor it has over the smaller M249, even if just visually speaking. My unit was stuck with M249s on convoys until we got our hands on some M240s for the gunner position. Now it seemed the average Iraqi driver, who probable has the same attention span as an American driver, would actually take note of the M240b on the turret and not get as carelessly close to the convoys. It may not have been as imposing as the ma duece, but it was good enough for what we were doing. Another observation I had with the M249b is that although it well known for it’s reliability, it can still fall pray to fouling if not kept clean enough. During an FTX, we were running thousands of blanks through them for a dry run, and than use actual live fire for the final run. Unfortunately, even though my ran fine when I had the initial blanks, by the time everyone went through the dry run (and probable no wipe down afterwards), the same 240B refused to cycle correctly with the live ammunition. But in fairness, that was the only time I ever had trouble firing the 240B in my military experience.

    • Uhhh dude all those pictures are of 240b’s, i don’t know were you saw an m60 or a marine carrying a 249. Every gun pictured is a 240b i promise you you’re wrong.

    • M60E4 I want to say. Also, the previous poster is right; that Marine in picture #3 is humping a 249. You can tell from the relative size and the shape of the buttstock. Typical TTAG journalism and attention to detail.

      • The guy wading, with the gun over his shoulder?

        It’s an M240. Take a look at the hinge for the (folded) bipod. That is not an M249.

      • Well as the person in the pic I have to disagree. That’s a 240, for one most grunt units issue collapsible stock M249s. Also I’m a big dude, 6’5 230 pounds, maybe it just looks tiny on me. Plus that’s a bandolier I[‘m keeping out of the water, saws use plastic drums

  11. I remember blowing 6-8 round bursts straight through a single man-sized target at 500 yards from a bipod and thinking about how badass the gun was. Luckily, I was a sissy 0311 and rarely had to carry one. Excellent review, sir.

  12. Outfriggin standing weapon. I never took a liking to the 249 (we gave them to our terps when we got in TICs. They would get up, shoot through the single magazine we gave them, and hop right back down and out of the way, proud to be in the fight) but lord I loved that 240. Great accuracy for its intended use and simply did not stop. It’s the gun that will outlast you.
    I got to shoot the 8mm MG42 out at my house about a month ago. I loved it, and I’m not usually a full auto fan. It makes total sense now that I find out it’s related to the 240. Crazy sound that MG42makes, like a reciprocating saw. Seems faster than the 240. Plus, 8mm Mauser. Dang.
    Oh, and I don’t know why the 249 was never as accurate, but none that I have ever fired have been. Anybody with a similar experience?

    • I think the M249 innaccuracy is due to a few things, first weapons age, our M249s were ancient. Next, the barrel latch system, take a M249 and you can move the barrel around, not like that with the M240. Thirdly, so many people use the barrel handle as a carryig handle, and it’s only designed to aid in barrel changes, not supporting the weapon

  13. I remember in 1985 I saw an M-60E3 for sale in a gun shop above a cigar store in Old Town, Alexandria, Virginia. They wanted $7000 if I recall correctly. I had several months of pay second lieutenant pay checks in my desk that I hadn’t deposited yet back in Quantico. I was very tempted to go and buy it. I’m still kicking myself for not.

    I’m curious as to anyone who has worked closely with both the M-60 and the M240 as to how they compare. I’ve fired the M240 but honestly, I’m not a machine gunner and there were two decades between firing each, so I don’t have a good feel for the differences.

    • Comparing the M60 and the 240 isn’t really fair. The 240 is pretty much the definition of a medium machine gun, while the 60 has always been a true light machine gun. The 60s biggest weakness was units using it way past its shelf life, and trying to us it as a medium machine gun. If you needed one guy to run a machine gun by himself, the 60 was your gun of choice(now the 48) if you use it in a weapons squad or mounted go 240.

      • I don’t agree with that assessment at all. Both fire the same round, the 7.62mm NATO and at roughly the same rate of fire, are generally the same physical size and use the same type of tripod. They are employed the same way and both are medium machine guns.

        • Their is a reason that a lot of SOF forces kept using the M60 family over the 240 for on man AW use. The 60 is smaller in weight and overall length than a 240, especially the E4/MK43 model with the short barrel. Look at the forward grip for the E3 and beyond models. The 240 was never meant for shoulder fired use. Again if you are using a tripod you are using a M60 wrong.

      • I don’t think M60 would qualify as LMG. At least if you look at the weights, it is still significantly heavier than pretty much anything else in that category. Hell, it’s heavier even than PKM, which is generally considered a GPMG. Compare to M249, RPK etc.

        I mean, if you want to treat it that way, it’s fine, but then it makes for a really sucky LMG just on account of weight alone.

  14. I am a gun lover. shooting is my hobby, i dont have gun neither. how i wish i joined the Marine. l really love to handle any gun that has the capability to suppress enemy positions.

  15. Got a chance to put a couple hundred rounds through one over the summer at Ft. Jackson during basic. Fantastic experience.

  16. My favorite job in the Army was being a 240 gunner. There was no funner weapon system IMHO, other than perhaps the Gustav…

  17. I just watched Korengal documentary last night on Netflix. One of the soldiers they were interviewing said his favorite weapon on the base was the M2 (ma Deuce), next the M240. What he said…

  18. My experience with the M240 was on an M1A1C Abrams. It serves as the rarely used loader’s machine-gun in a spray-and-pray type mount on top of the turret – and in the much more useful function as the coax mounted next to the main gun, fired by the gunner or the TC.

    It’s as the coax that you really see what it can do. It’s totally reliable and dead accurate at long range. If two guys are standing shoulder to shoulder and you only want to kill one of them – no problem.

    I love it almost as much as the greatest gun ever designed – the M2.

  19. “The broad butt plate gives you a good shoulder and cheek weld.”
    Sounds about the right description of my Ex.

  20. If you love to wear hoodies? so get this amazing Feel The Beat Hoodie Moreover, it has a hoodie-style collar with a pullover front closure and rib knitted cuffs to hold your wrist.

  21. This entire article is absurd. First of all you have to clean the 240 every 1000 rounds by hand or it will probably start to malfunction. Definitely not with a pressure washer, certain parts you want to be lubed and others (gas regulator) you don’t. If you have 10 mins to clean you hammer the gas regulator, feeder paws, and bolt rails. Also, a good weapons sqaud would have 3 240s, not 2.
