    Well made. Very impressed.

    Installs in seconds without hassles. Just drop it in and you are set to go. Works great. Placed over 500 rounds of high speed .22 lr ammo without a single issue. It just works reliably as advertised. (NOTE: Don't use subsonic ammo. It does not have enough pressure to cycle the bolt.) Mags are well constructed and sturdy. Cleanup is easy since the unit is stainless steel. What a great way to reduce the cost of plinking with your AR. A must get!

    CMMG .22LR AR Conversiin

    Dropped it in and worked flawlessly for 200 rounds. Purchased the .22 charging handle with kit. All three 10-round mags were loose, but fed ammo without fail.
