Gear Review: M-Pro 7 Foaming Gun Cleaner

M-Pro 7 Cleaner, c Nick Leghorn

The inside of a bolt carrier is the dirtiest, hardest to reach place in your AR-15 rifle. There are so many small nooks and crannies that the only way to thoroughly clean it is using a dental pick, a box and a half of Q-tips and about an hour and a half of time. The guys behind M-Pro 7 realized that structures like these are a pain to clean, and have come out with a foaming gun cleaner to take care of that particular problem . . .

The bottle uses a push operated pump to get things moving, which differs from the Break-Free CLP foaming cleaner offering (which is in a pressurized aerosol bottle) and means that it won’t explode if you accidentally puncture it. It’s not a major concern for most people, but if you’re planning on carrying a bottle in your range kit it might be a factor you want to consider. Also different from the Break-Free CLP product is that the cleaner is a pure white color and less greasy than the “I just poured this out of the bottom of my decades old toolbox” yellow liquid that Break-Free CLP uses.

Insert one end of the provided plastic hose into the front of the bolt carrier, give it a few pumps and the foaming solution quickly fills every nook and cranny of the object. Let it sit for a few minutes, then wipe off the freshly liberated dirt and grime with a clean rag and you’re good to go.

In my experience with the product, it worked perfectly. It cleaned out the interior of the bolt carrier without any issues and did a better job than I ever managed with my prodding and scrubbing. The only issue is the price: it runs about $3 to $4 more than the Break-Free CLP offering. But in my opinion, it’s worth the extra couple bucks.

M-Pro 7 Foaming Gun Cleaner

A little more expensive than the competition, but it works.

    A heated ultrasonic cleaner is the easiest way to clean the bolt.

    1. avatar mark_anthony_78 says:

      They cost a bit more than $15.75

      1. avatar Dan A says:

        Mine was 30 bucks, totally worth it.

        1. avatar OCD says:

          Do you have a link to that $30 unit or some info? ty

        2. avatar Tod says:

          Is this a small jewelry cleaner type? I’d like to see what you’re using too…

        3. avatar William Burke says:

          Maybe cheaper on QVC, but that channel’s reserved for when I can’t sleep. 15 minutes of QVC, and I’m out cold on the sofa.

          Guaranteed better than the Golf Channel.

        4. avatar Banana Ananab says:

          It was cheap. I guess they caught up with sales.

    Gas piston system FTW (runs and hides)

    1. avatar Wyfaggro says:

      That also costs more than $15.75

    2. avatar TangledThorns says:

      Exactly! With my LWRC M6A2 the BCG only needs light oil and brushing. Now I do use the M-Pro 7 Foaming when cleaning my rifle and pistol barrels followed by a bore snake. It’s a great combo and the bore shines afterward.

      1. avatar OCD says:

        I almost feel spoiled with my ldub A2 SPR. So easy to clean.

      2. avatar Mat says:

        Same with my Sig 516 and 716 except I’m a frog lube guy

    3. avatar Accur81 says:

      My Ruger SR-556 is pretty easy to clean – except for the piston assembly. Ditto with the CMMG M4 LEP II piston 6.8 upper. My buddy’s POF 415 is a snap, too.

      This looks like a good buy for my DI ARs.

      1. avatar CAG404 says:

        Accur81, yeah, agree that the SR-556 BCG is easier to clean than a DGI system. Pretty much remove it, wipe it down, oil it back up, and good to go. I use a .40 cal nylon brush to brush out the piston chamber up front. Does a pretty good job in getting anything out. I just scrub down the piston with the brush and CLP the best I can. Great reliable rifle. Never had any problems with it.

  3. avatar Matt in FL says:

    So many bottles of stuff reviewed here lately. It’s a good problem to have, but Nick’s shelf of gun-related liquids has to be starting to look like my girlfriend’s shower at this point. And I’m still just toddling along with my little bottle of Hoppe’s. For my guns, not my hair. Although…

    1. avatar Mk10108 says:

      Thanks for the chuckles

      1. avatar Chris V says:

        +1 LOL

    2. avatar William Burke says:

      You should see my hot sauce collection. I wonder if hot sauce works on gun gunk and grime?

      1. avatar John L. says:

        Isn’t that how you make tracer rounds?

  4. avatar jwm says:

    So, I’m guessing that a knotted bootlace and motor oil isn’t a viable option for cleaning these AR’s. Great apacolypse rifles.

    1. avatar mark_anthony_78 says:

      Bottles of gun oil will survive the apocalypse too, ya know… 😉

    2. avatar Davis Thompson says:

      Lots of folks use synthetic motor oil.

  5. avatar cutting torch says:

    Compressed air and a blow gun works better and faster than a rag, especially after a good cleaner, and it’s lint-free!

    I clean a lot of parts. I’m a mechanic.

    1. avatar OODAloop says:

      Blow gun huh? I really wanted one of those in middle school and had no clue they could be used to clean gun parts with.

      1. avatar Swarf says:

        Yeah me too. I was disappointed with what they actually did do.

        1. avatar scoutino says:

          They sure don’t clean guns. But blowguns can be usefull and fun. Some 15 years ago I used 4′ piece of 1/2″ copper pipe with 5″ of sharpened hanger wire with some styrofoam to seal and stabilize the dart. It went right through a rabbit. Instant kill, good dinner.
          Technique is important: do not blow. Use the tongue to plug the mouthpiece and build as much pressure as you can. Then pull the tongue back. When shot into hardwood I needed pliers to pull the dart out.

      2. avatar Davis Thompson says:

        I saw Martha Stewart shoot a blow-gun once. True story. And she was a damned good shot with it.

  6. avatar silverwarloc says:

    Hey, Nick. Would you use this on your SCAR 16? I’ve been using Hoppe’s on my SCAR 17 and for all of my hand guns.

  7. avatar Anonymous Coward says:

    Break-free isn’t for brakes . . . but for breaking 🙂

    1. avatar Matt in FL says:

      Haha, too late! I already fixed it!

  8. avatar Soccerchainsaw says:

    Scrubbing bubbles! Alright!

    1. avatar Rich Grise says:

      Beat me to it. 😐

  9. avatar John L. says:


    Drop in, swish around, walk away and do something else for half an hour.

    Come back, fish out, shake off, wipe off, lube, done.

  10. avatar Gov. William J. Le Petomane says:

    Hmmm…. for some reason I don’t have that problem with my mini-14.

    1. avatar Gene says:

      Gotta love the mini’s.

    2. avatar Davis Thompson says:

      Yeah, the Mini is an awesome rifle. I’m saving up for that adjustable gas block, though, so it’ll stop throwing my brass into orbit.

      1. avatar Gov. William J. Le Petomane says:

        Yes, I hear NASA is pretty concerned what with all the space junk floating around these days.

  11. avatar OODAloop says:

    Whatcha gonna use to clean the charging handle & the chamber/barrel? Can we see another 2-3 cleaning products reviewed tonight?

  12. avatar Swarf says:

    is a pure white color and less greasy than the “I just poured this out of the bottom of my decades old toolbox” yellow liquid

    Really? That’s a concern? Man, you AR nerds are weird.

  13. avatar Sixpack70 says:

    This is one reason why I like shooting my AKs. I go to the range, shoot, come home, wipe it off, and put it in the safe. My ARs, four hours later I might have it halfway done.

  14. avatar Michael Reed says:

    I have been here awhile but post little…. I actually enjoy cleaning my guns…Very relaxing to me… Q tips and all…

    1. avatar TNMatt says:

      I’m the same way, I actually look forward to it on the ride home after a trip to the range. Something about blasting chunks of lead through it and then making it look like it never happened after.

  15. avatar Southern Cross says:

    I used to spray the inside of the BCG with carburetor cleaner and then clean with a rag wrapped around a 5.56 NATO stripper clip. Clean again with another rag dipped in Hoppes solvent. And then with a dry rag.

  16. avatar 4IDsoldier says:

    So I guess no members or vets of the Armed Forces are on here? Shaving cream anyone??? $1.50 a can and does exactly what this does…Common sense from the military wins again. Just because it doesn’t have “for guns” on it must mean it doesn’t work I guess.

    1. avatar jwm says:

      Vet here from a different time. Never heard of shaving creme as a cleaner. Learn something new every day.

    2. avatar Yellow Devil says:

      Ah the old shaving cream trick. Well to be fair, I have done it a couple of times cleaning my M16, but I never made it a habit. My results never seem to be consistent.

      1. avatar 4IDsoldier says:

        You use the shaving cream. Let it sit in the nooks and crannies that are hard to reach. Flush with the hottest water you can stand and off goes the carbon and muck. Dry thoroughly (duh) and then dry again with a different completely dry cloth (for good measure) and then lube as normal.

        But honestly I spent about 27 months total in Iraq. LOTS of grimy, gritty, talcum powder-like sand that got EVERYWHERE in my rifle (M4A1 with M203 if it matters) and a quick wipe down and re-lube kept me fully functional in several fire fights, including 1 in the middle of a sandstorm. AR’s, both commercial and milspec are plenty reliable as long as they’re lubed in the right places and not completely full of dirt. Most civilian/ home defense/SHTF scenarios won’t have you going through the conditions of Iraq so I’m good without all this crap.

        Q-tips, cloths and a bottle of synthetic motor oil. About $10 worth of equipment can keep most guns you’d want in a SHTF scenario running for months.

  17. avatar jimmyjames says:

    Foaming bore cleaners changed my life. If I am really feeling lazy or completely beat after a day at the range, squirt some FBC, set timer on microwave for 1 hr, take nap, wake when timer goes off, rod out gun with dry patches, go back to sleep or head for the closest bar and grill.

    Hi there would you mind letting me know which webhost you’re working with?
    I’ve loaded your blog in 3 different browsers and I
    must say this blog loads a lot faster then most.
    Can you recommend a good hosting provider at a fair price?
    Thanks a lot, I appreciate it!
