    Been reading up on .22lr kits. CMMG kits seem to get great reviews and due to being out of stock everywhere seem to be popular.

    What kits do you guys use? Likes/dislikes? Those that the CMMG's, are they as bad arse as they seem to be in the reviews?

    Second question, are the mags interchangeable or are they proprietary between different companies?

    I do not like 22 conv kits in my ARs.

    1. They are dirty, you have to worry about cleaning your gas system much more.
    2. ARs are a slightly different cylinder bore and the wrong rifling twist for 22lr. So, they are inaccurate.
    3. Every conv kit i've owned and shot, are very finnicky and need lots of attention.

    If you get one, get CMMG stainless. Do not get the parkerized version.

    They are ok for plinking, but understand the issues that come along. A dedicated 22 upper or a AR 22 like the 15-22 are better for accuracy and reliability.

    Try to find mags with metal feed lips. Some black dogs have been breaking/cracking. You might want to google the issue.

    They are fun and worth the money, if you get a function kit. good luck.

    CMMG warranty is good, but they jacked me around for a while before they finally replaced my conv kit. After the bad taste, i sold the replacement and will not get another.

    Pass on the conversion kit and get a proper .22LR dedicated upper. You will not be disappointed.

    I have the old mil surp kit. My ar 15 with 1:9 twist is very inacurrate, but very fun. .22 lr is suposed to be 1:16. When I got mine dedicated uppers were very expensive. I would go with a dedicated upper now. If you do buy a kit the Aguila 60 gr sss works the best in mine.

    Gotigers said pretty much everything already. I think you would be wise to not feed a DI gun too much .22 ammo - after a few hundred rounds or so, fire a 5.56 round or two to clean the gas tube out. Replacing a gas tube is cheap and easy, of course... takes more time to remove the handguards than the tube.
    CMMG stainless kits are good. Do get the mags with metal lips, I've had one with plastic lips crack after being dropped. Looking at mags from other companies, it looks like they are interchangeable to me - it seems like everyone's building the exact same kit, just slapping a different name on it.

    I have a CMMG .22lr upper. It has not been perfect and has had a couple of OOB discharges which is really unacceptable in my book.

    I found adding the 'reliability kit' to it helped.

    I just went with a S&W M&P 15-22.

    I am very happy with that decision.

    I can only see one reason for a conversion kit, and it is the reason I own one. The aguila 60gr SSS rounds are very accurate out of my 1:8 twist barreled AR. It is just so much easier to swap the conversion in and out then to rebarrel my 10/22 with the proper twist.

    CMMG has very good customer service. Send it to them and let them take care of it.

    My CMMG dedicated .22lr upper has been excellent.

    If you have a 1:7 twist barrel, that little .22 bullet will spin so fast it will stretch itself into a .45 caliber orb, giving you greater stopping power.

    just kidding

    After paying $150 for the baseline .22LR conversion bolt, I have to say that they are neat, but agree with others to just "splurge" and get a dedicated upper. There are a lot of reasons not to get the conversion bolt and only one reason TO get it (cost). You can plink cheaply, but it won't be accurate, or reliable, or clean for your gun.

    I believe that the mags interchange.

    The baseline bolt will lock back on the last round, but only because the follower is jammed up into the bolt, so when you remove the mag, the bolt slams forward. This can't be good for the mag. The charging handle will still charge the bolt at least.

    If you do go with the conversion kit, I found that dri-lube on the rails that the bolt rides along was the best thing to use, no wet lube at all. I have been able to get about 99% reliability out of mine this way.

    I have a Ceiner kit for my AR. It is very easy to use and conversion takes about 30 seconds. It is perfect for my needs..plinking inside 50 yards. I probably have 1k rounds through it in the past two years with no issues to speak of other than the normal trials and tribulations associated with using cheap bulk .22lr.
    I don't think the mags are interchangeable but that could be wrong. Mine came with a 10 rounder and I purchased 2 25 rounders to go with it.
    I considered several options before I made the purchase. Buying a dedicated upper for $300, buying a complete rifle(probably the S&W) or a conversions. I did not want half a rifle taking up space in my safe. Since I was only using it for occasional plinking and kid shoots I wasn't concerned a great deal with accuracy so I went with the cheaper kit. Looking back I THINK I would have been better off just buying the S&W and having another gun. Since I bought it a couple of years ago I have purchased a S&W as well as a Mossberg Plinkster. The Mossberg is a piece of plastic that looks "tacticool" but 10 year olds don't care that it is plastic. The Smith is a nice little rifle to use with a silencer but it is $500 for a .22 which is outrageous to me. Smith magazines are easiest to load of the three which is a big bonus. All three go BANG every time(almost every time).
    Now if only .22 LR will get back to $.04 per round.
