CMMG perfects the drop in AR .22 conversion.

[Not_A_Llama]

Making additional AR's like your primary AR isn't hard save for optics and weapon lights. I easily and inexpensively equipped my AR15-22 w/AFG, ACS, Ergo Grip, ladder hand guards, MBUS and all the other goodies my primary AR15 has. I got one of the unthreaded bbls unfortunately so that's being threaded right now for a FH and it will also get suppressed just like my primary AR15. You see it as not being the same and I see it as being as close to the real deal as you can get.

This is just weird. You can't be saying that it's "easily and inexpensively equipped" when the sentence before you're saying it's hard for optics and weapons lights. A good optic costs as much as the M&P. Your little shopping list there is about $300 of parts on top of a $450 gun. That's a lot of money. Your accessories alone are double what I paid for my setup.

Know what's easier and more inexpensive? Not having to buy anything extra or having to move a damn thing off the upper you already have.

What's closer to the real deal than a replica? The real deal. C'mon.

i will buy the piece that Ridge Runner started the thread about. It will take the load of holding the bolt back off of the follower.

i forgot to add why I like the kit, other than price.

I move it from Ar to Ar. I have a few or more, and its nice to plink with which ever one i feel like at the time. Be it the K.I.S.S. M4gery, or maybe a midlength, or maybe the prarie dog rig.

Back to the original topic, I'd love to get one of these for the Appleseed, but its in a week, and I dont have much cash to spare after paying for a hotel room and tuneup for my car to make the trip :P

Oh well, still on my list of must gets for the near future.

Hello. I'm new to the forum. I'm looking for a conversion like the Ciener or CMMG for my S&W M&P15X, so I can practice with rimfire ammo as well as the fact that I enjoy ammo interchangability between multiple arms for versitility in my bug out bag. I'm not interested in buying a separate .22 rifle for this purpose, as I dont want to carry two rifles through the bush. I'm going to try to find a deal on a second hand unit that someone is no longer using, but I want to know if there are any specific brands or models that I should avoid? I don't want to accidentally buy one with a known bad reputation. I would like to be sure to get the best unit I can, but have read conflicting info on who makes the best one and what the difference in options is. Can you advise?

Welcome to the forum!

CMMG, Spikes and the others all use the same basic design. I went with the CMMG stainless kit because a local retailer had one for sale, and the surface was easy to clean.

i bought the brownells one.....came with 3 mags for 200 bucks they have a lifetime warranty on it which is nice because i had too return the first one after about 10000 rounds because of a broken extractor......btw anyone having reliability issues should just play around with different ammo till you find something it likes to eat

stupid question. so this is just a drop in thing, and you shoot the .22 out of the .223 barrel?

.223 is still a .22 bore barrel, so it's not that big a deal.

A true "22LR" barrel will actually have a nominal .221 bore, vs .224 in most centerfire barrels, but the slight difference in diameter does not affect the ability of the .22 bullet to engrave the rifling, and any high pressures encountered are easily handled by the more robust centerfire barrel construction.

It's available both as a drop-in for a .223/5.56 AR/M16 or as a dedicated upper or a dedicated complete rifle.

The dedicated uppers and rifles have true 22LR 1/16 barrels, and use a collar and true .22 chamber, as opposed to the .223 chamber adapter of the drop-in conversions. They're otherwise identical.

I understand the CMMG rimfire conversion is not as reliable as the parent AR 5.56 or the S&W 15-22. My question is will the CMMG fit and function with fairly good reliability in a Rock River LAR-15? I want the full weight, sights, and trigger of the RR.

Zoooombie thread!

But yeah, the conversion bolt fits right into the upper nice and snugly. It has it's own chamber extension that reaches into the bore so they don't just shoot into your chamber. They're not as accurate as .223, but it's a smaller bullet going down the bore. But they're good for short range marksmanship, and just plain trigger time.
