    Thinking about getting one for my AR-15. Mainly for ammo costs and for just plinking in the backyard. Anyone done this? If so how do you like it?

    I've thought about doing the conversion route but I finally decided that, for the 400 bucks or so that an M&P15-22 costs, it would be worth it to just have a dedicated .22 rifle. The main reason is to allow me to keep my actual AR clean and shoot the heck out of the .22.

    It's a great low cost shooting option! I used a CMMG kit
    for a few years, then bought a Spikes ST-22 dedicated .22LR
    upper. Love it! With the kit, you will get about 2" groups at
    50m. The dedicated .22LR uppers have proper rifling and bore
    to produce 1" groups at 50m. They arem however, a good bit
    more expensive.

    I've never used one, but it's interested me. I stay away because I presume there to be an inherently high failure rate.
    Did you experience a lot of stoppages FFA?

    I did the same....went with the M&P 15-22... even use it for local short distance practical rifle and steel matches. Fun, cheap and have it set-up basically just like my other AR's.

    A dedicated .22 upper will serve you better. 4 MOA is just not that accurate. You should be able to hold better than that in any position except standing.

    So this morning I picked up the CMMG Evolution .22 kit. Bought a 525 pack of .22LR ammo. Went and tested it out. Shot about 150 rounds and had 2 FTF. It was at the end of the shooting and I admit the rifle was dirty beforehand. Might be the reason for the FTF. The kit was $140 from the gun shop. I bought CCI blazer ammo as I read the Remington stuff causes problems. All in all it's a good little kit and cheap. From 25 yards, or less it shoots really good groups which surprised me. So I'm happy with the kit so far. I'm gonna clean my rifle really good and shoot some more. Hopefully that will help with the FTF issues.
     
  8. If you shoot lead bullets instead of the copper washed kind, put you bolt back in and fire 2 or 3 rounds of the real stuff every 200 .22lr.

    Otherwise you risk plugging your gas tube.

    I would just save the money and get a dedicated AR15 in .22 lr.

    Better yet, buy a Ruger 10/22 and a Troy AR Chassis for it. This is by far the best option because the 10/22 action is the most reliable in the .22 world.

    I never kept track,.....but I would guess about a 1% failure rate.
    Mostly due to crap ammo,........my Spikes really likes Stingers
    and Winchester. Does not really care much for Remington

    I have the Target Master conversion from Black Dog.
    It is reasonably accurate out of a 20" 1/9 barrel with Bulk Walmart 550 ammo.

    I have only shot it indoors.
    Easy to stay on a 25m Zero target at 75 feet (standing).

    It probably isn't a precision bench shooting tool.
    But I don't want to use a different rifle, different weight, sights, length of pull, trigger etc...I want to get cheap Trigger Time on my 'real rifle'.

    Negatives
    Double feeds (get good malfunction practice!)
    It gets dirty. (get good cleaning practice)

    Try a different brand of ammunition.
    Nearly all the .22LR conversion issues can be solved with better ammo.

    My Spikes does not run well at on on the Federal Bulk 550 ammo.
    It likes CCI Stinger, Fiocchi and I have had great luck with Winchester

    I'm going to try and shoot again today if the weather holds out. Cleaned and oiled my AR last night. Maybe that will help with the FTF issue. The ammo is CCI with 49 grain. So don't believe ammo is th eisse. I'm gonna shoot some .223 to clean out the gas system then shoot some .22

    Kinda fun shooting the .22 stuff. It's so quiet. Like a cap gun

    For that price why not just buy another AR-15?

    Now that I burned up the 550 I'm going to try a different brand.
    I have an Advantage Arms 22 Glock upper that recommends Remington Golden.
    Maybe those will work.

    I was using the Black Dog Mags.
    Kept having to drop the Mag and clear.
    Seems to start rough, then smooth out and then start to jam when it gets super dirty.
    I've run one box so far.

    For that price I would get a Nordic dedicated Upper (actually a little cheaper)

    CMMG kits were designed around Fed 36 grain bulk. That runs well in all of them I have seen. I liked mine, but I went ahead and bought the barrel and built an upper. It is more accurate and a better choice than the M&P.


    I had one of those and the flexing of the plastic can cause accuracy problems over time. The other thing that I didn't like was the lightly built bolt and extractor. It is not as robust as the CMMG stuff.

    I have a Spike's kit, and use it with Black Dog mags. The only ammo I have found that will run 100% is the Federal "Automatch" fodder...which is okay, as I can get it anytime at EvilMart. It gives good groups also. I am unconcerned with the lead bullets as I bought an M16A1 1-12 upper and fire .22s only through it.

    Accuracy in regards to what? I have over 4000 rounds through mine mostly for short distance tactical rifle matches and training. Today I and a buddy ran my M&P 15-22 in a local match over 450 combined in 6 stages. Not a single FTF or FTE. Every other guy in the squad not running a 15-22 but a conversion or dedicated 22 upper choked at least once or twice. The night before I was ringing 8 inch steel with the guys on the range at 200 and with my new 2 moa T1 mounted on it for kicks 2 inch 5 shot groups rested at 100 yards. I run only Blazer 40 grain RN lubed lead. How accurate does a 22lr AR platform have to be?
    I thought the real useful purpose of one was as an ammo saver training tool not a bench rest bullseye gun. I personally would rather have 22lr AR that ran reliably in dynamic movement.
