22LR converted AR15s can be very finicky. I designed this simple buffer weight replacement to help increase the reliability of CMMG and similar 22LR converted guns. This buffer replacement puts constant forward pressure on the conversion bolt carrier group, making the assembly unable to move in the chamber. Clips on to a standard AR buffer spring of your choosing, but I would recommend the cheapest one you can find since you are only using it for slight constant forward pressure. Save yourself money and weight off your build and print of these little guys today!
