Great for training and practice, this 22 LR conversion kit allows inexpensive target shooting through your favorite firearm. Shoots and functions like the regular AR-15, except the slide doesn't remain locked open after the last shot, with no significant change in weight and balance. Assembly is incredibly simple and only requires replacement of the original bolt carrier. No permanent modifications are required for use. Stainless steel construction offers the benefits of easier cleaning and greater corrosion resistance. For Semi-auto AR-15's only, will not work for M-16's.


  • Rimfire conversion kits are NOT compatible with gas piston equipped AR-15's. The piston will not allow conversion to fit in the receiver.
  • Light and subsonic ammunition will not operate as reliably (if at all), compared to standard or high velocity ammunition

    It is for a build that is not complete, how ever quality looks good, and arrived in a timely manner with free shipping.

    Works great. Took it to the range yesterday and fired it through a Radical Arms AR. Worked perfectly thru the 150 rounds i fired.

    The kit works great! Make sure to lubricate before first use. Ran flawlessly with cci mini mag, cci poly coated and even Remington golden.

    Tested it in 4 different ARs including 2 16" high end ARs, a 20" and an AR pistol length. Worked perfectly in all models. And it is quite accurate! All 3 mags I received are good quality and functioned well. I also used many types of ammo with no failures other than a few failures to discharge that were clearly an ammo issue.

    I was warned not to shop on this site, but everything arrived as fast as could be expected. I'm glad I took a gamble.

    Haven’t been happier!!! Best product with the lowest price ive found. Everywhere else wants more or only comes with one 30 rd mag or 3 10rd mags. This is best bang for the buck! thank you again
