Great flash hider for shorter barrel 308s - Advanced Armament Corporation Blackout Flash Hider, 7.62mm, 51t, 5/8-24

This version is definitely the best of the AAC 3 prong flash hiders. It indexes on the muzzle face instead of the shoulder behind the threads. This greatly reduces the “ping” sounds that is often an issue with pronged flash hiders. I also like that with the deep socket it threads on the barrel further and does not add as much length to the barrel. Plus on top of all of that you are set up to mount any AAC 51T muzzle accessories!
