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.
