Purchasing a new lower for a Dedicated .22lr upper.

[surfNshoot]

Long story short. I would like to purchase a stripped AR lower to build up for my dedicated .22lr upper. Main reason why is because I have not had a firearm purchase since probably 2013.

When I was at Turners I asked about using and AR lower but he said he doesn’t have a lower marked .22lr. Is this a requirement now?

Not a requirement

[Droops]

Not an ATF/Legal requirement, could be some sort of (silly) store policy. Just don't inform them on the type of caliber you plan to use.

I recall caliber "multi" is OK for DROS.

"Caliber: Monkeys Fly Out Your Butt" and almost anything else is OK. No requirement for caliber indicated on the lower...caliber is normally noted on the barrel somewhere.

Well, I guess this is a true statement - but probably also one from someone who does not quite know what they are talking about.

Normally, you are taking a regular stripped AR lower and building it out with an adapter in the mag well that allows a particular type of magazine. You are not purchasing a 22 cal lower like you would a 9mm AR lower with Colt or Glock mag well.

I suppose you could find a dedicated 22 lower in Colt or maybe something like a S&W M&P lower - maybe factory direct????? But why? The built out AR lower has more versatility in that it will run your 22 upper and if need be during a Zombie apocalypse could be easily converted to run a "featureless" or other CA Zombie approved 5.56 or other configuration. 😱

Check other threads in the Rimfire section on this topic. Also be sure to think it through and make sure in the future you aren't unintentionally creating an AW by slapping center fire parts on something that was an exempt rimfire with "evil features."

Good luck OP. AR 22s are fun!!!!

Find another shop to DROS. There are several manufacturers that roll mark “MULTI” caliber stripped lowers. Aero, Stag, Spikes, Anderson, PSA to name a few.

I think I’ll give em another chance. I wasn’t clear myself either. I see they have “multi” lowers in stock.

Thanks guys. Always appreciate the help.

This is one of those times that over-explaining to the shop employees is counterproductive. The caliber you intend to match it with is irrelevant to the purchase. All you need to say is "I'll take that one over there."

Eggzactly.

The less you say at Turners, the better. In fact, I'd HIGHLY recommend not even shopping there--the majority of the people behind their counters are complete and utter tools. But if you must... point, grunt, fill out the paperwork and pay. What you're building is completely irrelevant to them.

I wonder if they'll make you do the "safe handling" demonstration...

22lr upper. Taccom plug. Better mag adapter to use sw mp15-22 mags.20191221_222756.jpg

Umm...

Caliber "multi" is an evolution as the AR15 became popular. Old skul lowers
generally stated caliber.

I tried the Better Mag adapter and it didn't work on my dedicated 22LR setup.

I tried three different lowers (RRA, Stag and something else), and couldn't even get it installed, much less get it to the range. After some modification, I could get the receiver halves closed, but the bolt wouldn't cycle manually, nor would snap caps work.

Ended up going with https://arcatch22.com/, plus the shims you stick on the mags to get them seated tight. They now offer a clip on mag adapter you put in the mag well, if you don't want to buy the shims.

The folks at Ready Mag wanted to issue me a refund and return the product, but by then I had already Dremeled the hell out of the adapter, and that didn't sit right with me. You will have to replace the bolt catch, but it works really well for me.

There is no requirement that the markings on the RECEIVER matches the actual caliber of the gun.
The barrel of the 22LR upper will be marked as a 22LR and that will satisfy the federal requirements of the caliber being marked somewhere on the gun.

The easiest solution is one of these:

They accept M&P 22LR mags just fine.
