AR-15 with .22 Conversion Kit?

[AR22]

Mine will even shoot Winchester ammo, Even Remington, but I do not do it other than for testing to see if it will work,LOL

CCI is still my all time favorite 22 ammo.

Yes unless you have a anomaly, or are the luckiest man on the planet. Your CMMG pin will break, guaranteed..I keep atleast three spares around.

That way one breaks I call CMMG to send one or two new replacements. Always free. Cannot figure out why they do not find someone that can make them a new pin that works. I would think it would be cheaper than sending out new one constantly. But that is the only bad thing I can say about their products. So still good stuff.

I have to completely disagree with the run it wet with lube though. Very bad idea in any rimfire. Take my advice or not but adding wet lube in a dirty powdered round like a Rimfire is asking for instant sludge and a complete mess in your Rifle.

All my dedicated .22s and all other 22 Rifles I have, have only had dry lube ran in them for years. Wet is fine in a regular AR15 centerfire. Not a Rimfire.
Cleanup is a breeze running dry lube too and are far in between when running dry lubes also. Heed my advice or not. Up to you.

Sorry to get away from OP's legal questions, but since some of you guys mentioned it...what brand of dry lube do you use in your 22lr AR 15?

I have the CMMG 22lr conversion kit, but have not used it yet; my lower is a Colt M4 carbine with a notched hammer. Do you guys swap out the notched hammer for a round hammer (per CMMG's recommendation?) or just continue using the notched hammer with no issues? I'd prefer to keep the notched hammer in and not change anything to the lower.

Some people say they like the Hornandy One Shot dry lube. Have never tried that one yet myself.

I have used Rem Dri Lube alot in the past. I am trying something in a dry lube made by PB Blaster right now. It seems to be pretty good. I like PB Blasters other stuff so it may be a good product I think.

Try and see what the hammer does. Most will be fine. But I have seen a couple people claim they had troubles. Most do not. I think you will be fine though.

Im curious if these conversion kits would be legal in a pistol length AR, 10.5,12.5 ect.

Having owned a CMMG .22 conversion for a while now I gotta say it's fun to use and saves you a stupid amount of money. But it can be very finicky.

Trouble begins when you use anything other then your standard LR. If you want to use something like super colibri (500fps+-)you can expect it to not cycle but you will also find yourself clearing jams when the casings refuse to eject. So always carry a knife to clear it.

The other thing that happens a LOT, I mean a LOT. You will go through firing pins like crazy. The way it's designed causes them to break in half where the retaining pin sits. Also the tip of the firing pin also seems to break 1/4 from the tip.

Running it Dry really does work but believe me you want to clean it after every use because it will cake carbon all in the 22 chamber. Again causing casings to jam in the chamber.

I have thousands of rounds through my Ceiner/M261 kit with no parts breakage. I bought it used from a Calgunner so I have no idea how many rounds are through it.

I try to count the number of rounds I shoot per magazine so as not to let it snap on an empty chamber but I don't always manage to do so.

Going with dedicated upper, can anyone recommend a good inexpensive lower?

Did you want to build the lower from a stripped receiver or buy a completed lower? I built my last one from an Anderson lower receiver and its has served me just fine. Caveat I spent as much on the trigger as the rest of the parts. I just can't be happy with an 8-9 lb mil spec trigger.

Many LGS carry the Anderson receivers as a budget lower.

No issues with my CMMG kit. Works great, my direction to get the AW issue resolved. But I neve used the colibri rnds, no powder in them, primer only.

Never use Colibri in a semi auto, it won't cycle and you may have an extraction issue.

It does work great in my Henry Golden Boy.

-Dedicated .22LR upper (I built mine out of a scrap upper receiver and used the CMMG .22LR barrel with no gas port plus CMMG's bolt carrier group so it's undeniably a .22LR upper setup). You probably don't want to run a **** ton of cheap training .22LR out of your AR upper anyways, for starters twist rate isn't right for .22LR, and when people dump cheap lead tipped .22LR ammo through their AR uppers they can clog up the gas port over time. SOTAR (School of the American Rifle) showed this in one of their AR barrel autopsy videos. Seriously if you can buy a complete upper from Bear Creek Arsenal for $300, you can probably do a dedicated .22LR upper for around that much or even cheaper. My cost was low but I was digging through my scrap AR parts bin for stuff.

-Cheap lower receiver with .22LR plug, so if anyone cracks it apart you can insist it really is used for .22LR only. Poverty ponies (Anderson) is only like, $40, and there's polymer lowers out there for about that price too if you want it even cheaper. It's not like .22LR hits the lower with any appreciable amount of recoil. https://borebuddy.com/product/22lr-plug/

Any lower will be fine. I would avoid the plastic ones though. I know some will claim they used a plastic lower and it is fine. Good for them. But they are supposed to be aluminum. And for a reason,LOL No way those Plastic lowers will last in a hard run Rifle for sure and very sketchy on a light used Rifle too. Not worth it to even consider Plastic for the few dollars you will save.

I have used many different ones, CMMG, PSA, Anderson, Aero and so on. Never a problem with any of them.. More less just buy the Logo and markings that may appeal to you. It will be fine.

I believe Aero and maybe one other company only, really makes most of the lowers. They are then finished and roll stamped by whoever buys the lower to finish it up for sale by their particular Company. Some do a nice refined job of finishing them out, some a little less attentive. But they work as they should.

[Jimi Jah]

My lower is Aero. The buffer and spring were removed to lighten it up and make it rimfire only. Then the adjustable stock and pistol grip were attached.

Where do you put dry lube on the ar22? Are you talking about the bolt specifically?

I have been putting a little gun oil on the bolt carrier rails, firing pin, extractor pin when I pull the bolt apart to clean. And the usual AR15 maintenance lube points.

Where would you suggest switching to dry lube? Or switch to dry lube for all?
