Was looking at the CMMG Bravo .22 LR AR Conversion Kit, https://palmettostatearmory.com/cmmg-22arc-bravo-22lr-conversion-kit-22ba651.html, and almost ready to pull the trigger (pun intended) on it but thought I’d get some advice from those that know much more than I do. It was either this or a Ruger 10/22 but this will allow me to use my AR to get more practice with using it. What are y’alls thoughts on this?

Cmmg makes good stuff.

Looks like a good deal.
Our M+P 15 .22 mags are $30 + and that deal has 3

I bought one of those kits to train with my ARs too. I don’t know if it’s barrel twist rate etc but it just wasn’t accurate enough out of any of my uppers. It was still fun at first, but ultimately had more fun with our 702 at my gun clubs rimfire range. I’d still get the kit regardless……just because it’s nice to have that option with a rifle or rifles you already have

I have one and use it a lot. No it’s not as accurate, the twist rate is too high for a .22 LR, but for me it’s good enough. I would not run any LRN though a 5.56 barrel though due to lead fouling. I usually run several 5.56 or .223 afterwards just to knock the crud out of the barrel, .22 LR are very dirty.

I got one as well, it’s fun but the twist rate is definitely not even close to ideal and of course I have to adjust my optics when switching from .22lr to .223 and back again. I get good accuracy out to 25 yards which is all I expect from it . As far as less expensive practice, keep in mind there’s no recoil to speak of. To me, it’s important to feel and control that recoil. Otherwise I might as well be doing dry fire practice. It’s fun to shoot and I get a stovepipe from time to time but, it’s fun and inexpensive.

This is of interest to me also and almost went for the CMMG conversion kit. Then I spent a bit more time researching online and learned about fouling and rifling issues. Putting on a different upper with a barrel designed for 22 rimfire sounds like a better idea, such as this ATI complete upper, UPC 813393011986 per PSA’s website, but they seem to be perpetually out of stock.
This might be why PSA is out of stock on the 22LR upper assembly. According to some other website, the ATI upper assy is “no longer available.” The same website says the product brand is American Tactical Imports. No thanks. American Tactical imports cheap stuff from China. Well now, this is interesting: ATI is in Summerville, SC. Huh.
Does anyone know where that CMMG kit is made? I found out that CMMG stands for Central Missouri Manufacturing Group. Some websites really seem to talk them up but here is one site that has negative reviews.
Another option I had looked at was getting an AR15 style rifle in 22 rimfire, such as the Smith and Wesson M&P15-22, or the Walther replica of a Colt M4 in 22LR. Both seem to get decent reviews. The Colt seems like a bargain at under $400 for a complete rifle and forget fiddling around with conversion kits. Hmmm.
An AR-style entire rifle in 22LR costs more than a conversion kit so that’s a plus for the kit. I also see the value in training with the same rifle you are familiar with, but being able to punch paper with ammo that is much cheaper for practice, so that’s another plus for the kit. Minuses for the kit might be product quality, fouling, and accuracy.
It is possible to build your own 22LR upper from parts also. This would take care of the rifling difference and fouling your 5.56 barrel. CMMG offer an AR15 barrel in 22LR, plus a special bolt carrier group and the special magazine. I’m looking at one online reseller and put all three items in the cart. The total is $391 plus tax and shipping. I guess you would still need an upper receiver, handguard, barrel nut, delta ring, charging handle, etc. Seems like buying a whole rifle is cheaper than building one if you don’t want to go the conversion kit route.
I guess bottom line is take a chance on the CMMG kit and see how it goes, or buy a complete AR-style rifle in 22LR. I think I’ll just stick with my Ruger 10/22 for now, although that Walther/Colt M4 in 22LR sure is tempting! Great question that has given me some new ideas for… ahem… what Santa should bring me.

Thanks everyone. Now I’m kind of leaning away from this because of the lack of accuracy due to barrel twist rate, and the possibility of lead fouling up the works limiting the ammo choices. Maybe I’d be better off just saving up a couple hundred more and getting the M&P or 10/22. Good excuse for another rifle, I guess. Decisions, decisions.

I have one, but I prefer to shoot my M&P15-22 more.
The issue I have with the conversion kit is that you tend to get some accuracy issues after lead builds up when you shoot a lot. Keep in mind that the twist rates are very different for 22lr tham for 5.56, so there’s going to be accuracy issues. But for shooting 25-50 yards, it’s good. And don’t expect to shoot a 500rd pack through it without experiencing some lead build-up.
That said, you simply clean it out by shooting some 5.56 through the barrel.
I see everyone else already said all this, now that I have read the rest lol

I can honestly say that shooting the cmmg equipped rifle is fun, BUT, I will probably end up buying a dedicated .22LR upper at the least and setting it up like my 5.56 . Then it’ll be 2 pins, swap the uppers and I don’t have to spend time adjusting sights and it will be more accurate.

You can always use another rifle, especially a 22 rimfire since it’s cheaper to shoot. You see: you are actually saving money by buying another rifle because you’ll spend less on ammo over time. That’s called government math or shopping logic according to individual preference.

I’ve been very happy with our S&W 15/22 .
Good accuracy from a semi .22 Ours came as a package deal with some extras- M lok handguard + scope.
It does out shoot our 2 10/22’s but not our Marlin 60.
Don’t forget to look at the Tippmann - My friend has one and I like it very much, it would be on my short list if we didn’t have the 15/22

Last weekend I picked up a Rossi rs22 for 115 bucks at Wally World, and also finally took the plunge on my first 10/22 that weekend. Already have a mossberg 702 for nearly 12 years. The cost of that Rossi is significantly less than the cmmg and far more accurate. Shot close to 500 rounds so far and not a single issue. My cmmg bolt needs cleaning or at minimum a quick blast of clp after less than 100 rounds or just doesn’t work. Yes, it was cool at first so we could practice with an AR a lot, at our clubs rimfire range, but then I built a 9mm AR and can shoot that anytime at our pistol caliber range . All those things combined really hindered the desire to use the conversion anymore

Been looking at this idea a few months ago. Most people said the twist in AR is inaccurate and kinda meh. So I kept thinking about getting a threaded RS22 and getting the folder but they’re always OOS.
Now I’m leaning toward the BCA complete upper. It’s just like this kit so you don’t need a buffer, 3 sizes of barrel to choose from and a complete upper so fast swap or dedicate it for kinda cheap too. Only $230 with discount and possible free shipping with a few other buys. Uses the same CMMG mags which are 5 for $60 from MMC/DTT right now. Or $15/ea as singles.
Cheaper than a new charger or threaded 1022 if you can find one but same thrills. Plus no tax to a ■■■■ state and no paperwork, fees or double taxes with an 80 lower.

RS22 threaded barrels are offered from Rossi for just $50 FYI. Unless you got the threaded already. Side folder stock available from Promag. It’s the same stock/gun as Mossberg Plinksters. Or the Trakr stock will work on it also.

I have a CMMG 22LR conversion and love it. I use it to get range time for my AR. I just cannot afford to shoot much of my 556 ammo, so the CMMG kit helps a lot.

I have the conversion and a BCA dedicated 22lr 16 inch barrel upper. for accuracy go with dedicated upper, for first time user of AR platform, using to train or tp plink at the range of a lot less money go with the conversion.
each one of them have a purpose. the conversion gives 2 calibers with one upper in case SHTF.

I have the CMMG (American made 100%) conversion, works great for training, not a solution built for long range accuracy it’s to give you a 50 yard AR platform for CQB type training

Like everyone has said it’s fun but not very accurate due to twist rate. I ended up building a dedicated upper with cmmg 22lr barrel and it’s on point. Also not having a gas port I can run anything through it without fouling. It’s more $ of course but it’s nice to just swap uppers and have an accurate 22.

I had a M&P 15-22 but sold it off. Just didn’t care for the plastic. Built a 22LR specific rifle and love it. Using magazine adapter to use S&W magazines. Actually my PFG is host lower for that build.
