Looking for complete AR15 in 22LR caliber

[gaoskddm]

I'm looking for a complete AR15 in 22LR caliber. Some candidates come into my mind include Kriss Defiance DMK22C, CMMG resolute 200, Colt M4, and S&W M&P 15-22. I wonder what brand and model you guys would recommend based on quality, durability and accuracy. Thank you!

I've heard a lot good stuff about the M&P 15-22, but I'm just not very interested in polymer frame.

Another question, is the area where the buffer normally resides blocked off in 22lr version of all brands? e.g., dmk22c
I think M&P has the same style.

I wouldn’t get the m&p. If u ever wanted to change calibers you couldn’t. Instead buy a standard lower and then figure out what upper to get. Might cost u more but at least you would have options

Would it be legal to have a standard lower + 22lr upper with all evil features on it, e.g., pistol grip and adjustable stock? I talked with two local dealers about the lower part. One said the buffer area has to be blocked. Otherwise, the owner is able to convert it into other centerfire caliber ...

Any suggestion? Thanks!

What is wrong with polymer lower? Its a 22lr... nothing high powered. And I've yet to read about polymer being a problem on the MP 15-22.

With regards to your question, you can definitely run your rimfire rifle fully featured with detachable magazine and adjustable stock. The problem you will run into is if you try to have multiple uppers on a shared lower... then you will probably need to figure out how to stay in compliance with current AW regulations. Rimfire rifles are exempt from CA AW regulations, but as soon as you install a 223/556 upper, you will have issues.

I have 15-22 and it is a great rifle. I have yet to have one failure on it with bulk ammo. I clean it every 2 trips to the range and go thorough about 500 rounds each trip.

Highly recommended it

I’ve been running a CMMG conversion with a Freedom kit on a standard lower ( which can easily be removed). Works great and can go from.22 to 223 without issue.

Now days buying a mil spec lower its going to get registered as 223/556 unless you get one of the few stamped "multi". Years back I was able to get one unstamped caliber and one stamped 22LR but DROS was only long gun then anyways.
Now days going with one of the non-mil spec 22LR only would avoid any risk of noncompliance.

I have a S&W M&P 15-22 and like it. No issues for me except it is "no Bueno" for Appleseed.

I have a dedicated .22 PSA upper on a standard AR lower. I like it better.

On the first couple of pages of the Rimfire Forum there are at least 4 - 6 postings about dedicated AR 22 rifle vs dedicated upper only vs CMMG conversion, etc. Also note discussions about possible legality questions. IMHO it is worth your time to read them BEFORE making your purchasing decisions. All are viable candidates but like most things related to firearms can have different feel and usage components that have to be evaluated in the context of "what works or is right for you."

Good luck on your travel through the .22 cal looking glass

The concerns regarding the polymer framed 15-22 lower are valid. That model is OK for the casual "shooter class" of people who will handle it gingerly and shoot it occasionally at an indoor range.

Most folks in the "operator class" like myself would not have much use for such a firearm. Indoor AND outdoor shooting, rough handling, and extremely high round counts (1800 - 2000 rounds in a single year!) and that thing would be toast if subjected to such insane operational demands. But I do acknowledge it could be useful for the weekend plinker types.

Thank you all for the suggestion! I'll start reading previous postings before I make my decision. Probably, I will have more questions to ask.

Ar15 lower is multi caliber

Get a dedicated 22lr upper. It uses a hybrid bcg, and a 22lr. Barrel. No spring or buffer, unless you keep it for weight. I also run a taccom plug. I have the boonie packer better mag adapter to run s&w mp15-22 mags.

There are no issues with legality

It is not, what it isn't


Some people may trip, but some people wear tin hats and are afraid to leave their parents basements too

I love my 15-22

I've had the Colt M4 for several years, it's a good shooter. Cleaning it is a PITA. I prefer my 5.56 with a conversion bolt.

Curious how you run the taccom plug with out the spring and buffer. I thought the thats what keeps tension on the plug?

Dedicated .22LR AR. I run a TacSol upper.





Just snap the .22 upper onto ANY standard lower, and you're GTG. By the same token, if the poop impacts the rotating oscillator, you can pop the .22 upper off, and pop a 5.56 upper on, and you're GTG! No changes, no tool - pop the pins, and you're changed over in seconds!
