Description
These parts help to further reduce gas blowback (especially on conversions) and prevent casings from becoming lodged in the charging handle channel. Patented.
Designed to fit rifles and conversion kits with a CMMG/Atchisson/Ciener style bolt.

With a standard charging handle, my rifle experienced A LOT of brass over bolt jams. I purchased a CMMG anti-jam handle, which eliminated the problem, but it was like a plastic Mil-Spec handle with a small pattern latch. It just didn’t inspire much confidence. I bought one of these inserts to use with an SI Extended Latch Charging Handle. Snapped right in without a problem. It works perfectly, and can be operated with one hand. Excellent product, you won’t be sorry.

Perfect innexpensive upgrade. When using a standard AR-15 charging handle (Expo Arms mil-spec and Radian Raptor), I had lots of failures due to spent cases getting stuck in the charging handle channel. After dropping in this simple part, I have not encountered a single jam in the charging handle channel from around 500 rounds fired. Super easy to install, and 100% worth it.

does the job but constantly rides forward on its own. i dunno if it affects the cycling somehow but i know the installation says not to have the insert all the way up.
