As with all 308 ar parts, do your homework - Precision Reflex DPMS G2 Gas Buster Charging Handles

This part does not fit an Aero M5 or PSA G2 upper. Part 3AK-CGH-GBCHLL-03-072-05 looks to be the correct one. I will be exchanging. I ordered a forearm and full top rail for my Aero M5 build. We will see how that goes together. Precision Reflex suggested the Armalite top rail to account for the high profile upper receiver. These parts are obviously good quality, just did not fit. All 308 parts vary, just ask before you buy.
