Does anyone know where I can get a good quality complete A2 .22LR upper for my AR15?

Stay away from the canned .22 uppers and you'll get over it in a couple of weeks.:D

DPMS has one with an A2 configuration, the AP4 .22.

Midway USA carries them, cheap too if you have a C&R discount.

is there a reason you're set on the complete upper? i get pretty decent accuracy out of my ciener conversion and it's alot more compact and convenient. i've heard it said that dedicated uppers are more accurate and this is probably true, but we're not talking about a huge difference 'cause the conversion turns out tight enough groups. i didn't formally test it but it shoots at least as well as my two savage .22 autos. it's also stone cold reliable. oh, and half the price of a dedicated upper.

I could be wrong but I believe DPMS is the only company making .22LR uppers in A2 config.

Check out some other threads here, or take a look at their website. Bushmaster makes an A2 20" 22 lr upper which I keep thinking about getting, although it's like 4 or 500 bucks.

Do you have a link to it? You are probably right but the only .22 BM upper I've seen is a 16" model with some kind of funky A3 type upper. Do the BM .22s use the same mags as the DPMS or CZ uppers?

It sure looks like a standard A2 upper to me...I just can't seem to find anyone, anywhere who actually owns one, shoots it, etc.

Boy I'm a dumbass. Don't know how in the hell I missed that? :confused:

I stand corrected. Thanks :)

There are a lot of reasons not to use the Ciener kit. First is it could baddly plug your gas tube with lead. It could damage your barrel. I ruined a carbine barrel when I had a 22 bullet lodge in the barrel and fired another one behind it. There is no real recoil so I did not notice the difference in report. The action cycled and the bullet lodged just 3 inches shy of the end of the barrel. The second bullet rammed in behind it and buldged the barrel a bit. I did not notice it until I cleaned the rifle.

Accuracy is also another reason. It varies from gun to gun but my rifle grouped about about 3 inches at the 50 foot indoor range. My Bushmaster 22 upper groups about 3 inches at 50 yards.

Personally I cannot recommend the Ciener kit.

that's good to know. i shall be very careful with mine and i won't be using it in my better uppers. thanks.

if you use jacketed (they're really plated in .22, aren't they?) bullets and clean it well before firing 5.56mm there shouldn't be a problem with lead build up, though, right?

I have considered this myself, the best alternative I have seen bang for the buck wise is the CZ upper for a bit under $300. but there are several problems with reliability and durability, the latter being with the magazines and a tendancy for the magazine mounted ejector they all use to break pretty easily. You can build up a custom 10/22 which is a better .22 all around for about what an upper costs (no I'm not talking a volquartsen franken gun for $2000).

A fellow at my club who is an accuracy freak and a match competitor for many years did lots of research and ended up buying one from Accuracy Speaks. They are a custom gun shop, they use a ciener conversion and they build an upper around the conversion which is machined and fitted to the upper, the upper uses a .22lr match barrel with a 1 in 16" twist.
But you are talking $1000-1200 for that option by the time you are done with magazines and all.

The problem with just using a ciener conversion in a regular ar is the barrel, the twist rate of 1 in 7 to 1 in 9 for an .223 barrel will produce very poor accuracy. You really need a .22lr. barrel with the proper twist rate to get good accuracy.

I have also read good reviews for the DPMS upper which is a dedicated .22 upper with the proper barrel but I have never seen or fired one.
