ACME Machine is a relatively new entrant in the firearm parts, accessories, and optics business. They’ve been around for a couple of year now, while their parent company, Global Precision Parts (originally known as ACME Machine Automatics), is over 30 years old. I have gotten a chance to review some items from ACME Machine over the last year ranging from optics to accessories, most have centered around the AR-15 platform.

ACME Machine is deep into AR-related gear and equipment and, and they do it well with budget-minded AR builders in mind. They do a lot of off shore manufacturing to their own specs when it comes to optics, and certain other AR accessories and their prices reflect that.

For some firearm parts, that are much more critical to fit and finish, they source bolt carrier groups, receivers, and barrels through American companies, producing American made components. I have used their handguards, and a full lineup of their optics, and I can honestly say, considering the price-point, I have always been pleasantly surprised with the overall fit, finish, and performance of the items I have tested and evaluated. But enough about all of that. This review is about their new line of optics for shooters that want to really reach out and touch something.

They have a new line of affordable optics for those who need to reach out and touch something and I got my hands on their 6-24×50 First Focal Plane Tactical Rifle Scope. The optic has an official MSRP for $599, and as I am writing this, the price online is $349.99. I have even seen it available as low as $299.99.

Some people love optics at this price point, while it serves as a warning to others who wonder how a first-focal plane design scope that’s worth a damn could possibly sell for that price. While the price point should definitely raise some eye brows, as I’ve seen, the quality for the price point here will also raise a few.

As you’d expect with from a budget-priced optic, the 6-24×50 is made off shore in China. That will no doubt turn some people off, and, honestly, I get it. I’ve played around with some cheap budget optics made of “Chinesium” and was greatly disappointed at both the reliability and performance.

But, I can also say that Chinese manufacturing has come a very long way in the past decade. Companies such as Atibal, Athlon, Primary Arms and Vortex have demonstrated that, when managed well, off-shore manufacturing can mean shooters get a lot of performance for their dollar.

Even the 6-24×50’s packaging is a step in the right direction. It’s a solid box with a magnetic closure and has their logo on it. At first glance, the scope’s glass was very clear, and the side focus adjustment was tight, but also smooth when rotating it. The side focus knob doubles as the brightness adjuster. It has an “off” setting between each brightness level which is a nice touch in a budget optic.

ACME Machine 6-24x50mm FFP TR Scope Turrets

The windage and elevation turrets are tactile, and have audible clicks for each adjustment which are set at ¼ MOA. The windage and elevation turrets are also capable of being taken off so that the shooter can “zero” their scope after your dope is properly set.

The magnification adjustment moves smoothly without any grit or creep. As mentioned before, the scope’s TR-MOA reticle is on the first focal plane, so when the shooter increases magnification, the reticle also zooms in closer. That means a reticle that stays constant in measurement with each hash mark, or stadia line. Each stadia line remains a measurement of 1 MOA, regardless of the range. The optic has 60 MOA adjustment for elevation and windage. ACME Machine claims it is nitrogen purged, o-ring sealed, and waterproof.

To test the adjustments on the scope, I did the standard 100-yard box test. If an optic doesn’t have reliable, repeatable adjustments, then you’re wasting your time when it comes to longer range shooting. It’s the acid test as to whether a budget scope is actually worth anything.

ACME Machine 6-24x50mm FFP TR Scope

I mounted the  6-24x50mm FFP TR scope on a rifle I built for more precision shooting, along with dispatching groundhogs and coyotes on my family farm. It’s chambered in .223 Wylde with a 416R stainless steel, 20-inch barrel supplied by Rick Hoffmeyer at Radical Barrels, LLC

The load I used was 77 grain IMI Razorcore, in three-round groups. On a good day, and if I do my part, I can keep .4 MOA five-shot groups with this set-up, so the barrel and load were proven.

To begin the test, I started out dead center. Going from of my original zero, I then made 16 clicks left and 16 clicks down, sending my next three-round group at the bottom left target while holding on the center bullseye.

I repeated this process, using the appropriate amount of clicks shooting for each corner target while maintaining a hold on the center bullseye.

ACME Machine 6-24x50mm FFP TR Scope Box Test

As you can see from the target that I shot at 100 yards, the scope tracks was dead-on. My final center target shot was less than .4″ low from my original dope. Considering the price point of this scope at well under $400, that’s impressive.

I’ve only reached out to 300 yards with the ACME Machine 6-24x50mm FFP TR, which is about par for most shooters. Even then, ringing a steel torso at that distance has become boringly regular. Using the MOA hash marks and knowing I have about four minutes of angle drop at 300 yards with the load I used, they’re accurate.


This optic comes feature packed for the price. The light transmission and clear glass are on par or better than other optics I’ve used that were made off shore. The side adjustment focus is easy to use, and the “off” settings in between each brightness adjustment is a plus. The optic comes standard with surprisingly solid, flip up caps that are a tight fit. The reticle is easy to see at full magnification and is equally easy to use. This optic also comes with a limited lifetime warranty through ACME Machine.


The field of view isn’t the best I have seen, but it’s still usable. For the price point, it would be hard to upgrade to a wider field without increasing the cost substantially. The finish on the tube looks cheaper than other budget scopes I’ve seen. It’s more of a matte finish, than a flat, and has a small amount of glare to it. That by no means affects function, but it’s noticeable compared to higher-end Vortex, Nikon, or Leupold optics.

Ratings (out of five stars):

Build Quality: * * * *
While the matte finish isn’t the best, for the price point the scope is solid and adjustment knobs don’t feel cheap or have any play in them.

Optical Quality: * * * * *
Based on the price point, the glass rivals higher end Vortex, and even lower level Leupold optics.

Adjustment & Controls: * * * *
Adjustments are rock solid and sure considering the price point. Not perfect, but pretty damn close.

Overall: * * * *
While this optic won’t be competing against anything from Nightforce, Schmidt & Bender, or Kahles, for the price point, this first focal plane optic with illuminated reticle is a hell of a deal for someone on a tight budget, or just getting their feet wet in longer-range shooting. The glass is very clear for an import optic, and adjustments tracked well.

  1. Despite the admittedly impressive box tests, the fact you called the parallax adjustment knob the “side focus” makes me a little leery of trusting this review.

    • Forgive me. I’m definitely not an avid long range shooter. My bread and butter is more of a defensive style of shooting that I continued on from the Marine Corps. My “longer” range shooting is about 400 yards, and is limited to paper punching, ground hog shooting, and deer hunting. Definitely used the incorrect term. I apologize.

      • Fair enough. If that’s the case, the small discrepancy in the box test may well be because of an improper parallax adjustment. Overall, good job. I apologize if I came off too harshly.

        • My apologies to you also. It upsets me folks put in the time to write an honest review and folks trash them. I prefer amateur reviews to the pros. I shouldn’t have been snappy towards your comment.
          Some folks just look for fault instead of encouraging or helping others to improve their writing. Thank christ we don’t have grammar Nazis here lol.

  2. Seems to be a pretty decent scope so far. I am satisfied with the scope, it’s not perfect, however for the price I can live with it. So far it hasn’t fallen apart yet and everything is still working as well as when it was purchased. Take care in seating the rings however as the tube seems a little thin and could possibly be crushed.

  3. The last box test I did was on a used optic I picked up at a show. I can not even recollect when I did one on a NIB scope. On the other hand I also don’t use a D.O.P.E book to hunt deer. Looks like a Horus copy probably pareidolia on my part.

  4. Mr. Whitmore, thanks for the review.

    Most shooters will find that if the parallax adjustments is used as intended, and not as “side focus” their groups tend to diminish when shooting over varied ranges.

    Also, only the lowest model Vortex, the Crossfire, is made in China. The Diamondback and Viper lines are made in the Philippines, and the high end Razor line is made in Japan, just like Leupold. I’ve found the Razor class quality to be every bit equal to the top end of Leupold’s glass.

    • jwtaylor, I am aware about the optics from Vortex. I own a Diamondback that has served very well for deer hunting. I was speaking more in general to Vortex’s line. To my knowledge, all of their red dots are made in China. Clarity of this scope is on par with my Diamondback 4-12×40, but twice the magnification. And thanks for reading!

    • Just a cheap set from Wal-Mart. Its worked fine out to the ranges I typically shoot. Saving up for a better quality ADM mount.

    • I was wondering how long it would take before the inevitable Wylie Coyote reference would appear. Thanks.

    • Honest question, do you think Vortex, Primary Arms, HOLOSUN or Atibal is junk as well? Because honestly for the price point, they hold their own. I have handled most of the models from these companies that are imported from China. I’d never compare them to say Aimpoint or Trijicon, but then again, its not a very fair comparison because they are in completely different price points.

  5. Interesting and great review

    I like the fact that it tracks well. Id like to see more details on the glass quality at longer ranges.

    My only concern is durability. While I dont look for Tier 1 operator levels at this price range, Id want to be sure it can stand up to the normal stuff like a little rain, or repeated heavy fire on a rifle.

  6. Y’all,
    Got’s me the Nikon Black FX 1000 on my 6.5 CM tack driving 500 YDS and 1000 YDS No Problemo!
    On the AR-10 got’s the Nikon M-Tactical 3-12X42 tack drivin 500 YDS , PAPOW !

  7. I was just wondering how the scope is holding up since the review? A year later and there on sale for $299…. even though I don’t need a scope right now, I may grab one while they are cheap and available. I know it won’t be long before I need another piece of glass.
