I have shot about 200 or so rounds with a few different ammunition and this conversion kit has worked flawlessly. I had few failure to extract from the bulk boxes but that's to be expected. This definitely worth the investment as it makes it very cheap to shot and it pretty fun.
<br>My only negative is that the BCG had a very hard time fitting all the way in my upper receiver. I have Palmetto State upper. Now the only way I was able to get to sit all the way in was to lightly sand the bronze circular thing (or whatever that piece of metal is ) and literally pound the BCG in the receiver so it can fit flush. I had to this about 30 times rotating that piece so it can come easy. As of right now I don't have pound to much. I just use the spring power in charge handle to put in place. Taking out of upper receiver is a bit difficult. Over time it will eventually be all evened out for my AR15. At this time I'm enjoying the crap out of it

a must have for any ar15 owner.


great kit at first i wa worried because of constant jams..feed no fire or stove pipes or no fire. but once i hot around 150-200 rounds it was going through mags no issue. ive put around 2000 so far since i purchased it and very happy with it easy to clean and use. built a whole new upper just for this kit. others that shoot it are shocked an ar can be converted to shoot 22 so easy.

Awesome Conversion Kit for Any AR-15 Rifle

This is well worth the purchase in my opinion. I was able to shoot 250 rounds of .22LR through this BCG the first time out with only one FTF. I shout Remington Hollow point Rounds through it. I used a 18" 223 Wylde Barrel, 8.5" 5.56 Barrel and a 16" 5.56 barrel. This thing allowed the .22LR to shoot on paper so well. I have found a new way to shoot my rifles, but at a much cheaper rate now. Thank you Primary Arms for the sale price and thank you CMMG for coming out with this.
