**THIS KIT IS FOR CONVERTING 5.7X28MM TO 22LR ON OUR 5.7 CONVERSION UPPERS ONLY AND WILL NOT WORK WITH .223/5.56 CHAMBERED RIFLES OR OUR MK57 LOWER**

Easily convert your CMMG 5.7x28mm Upper Receiver Group into a .22LR in seconds! The new Mk57 .22LR Conversion Kit is simple to use. Just remove the existing CMMG bolt carrier group from your 5.7×28 upper and replace it with the drop-in conversion.
