Advanced SilencerCo ASR Style QD Muzzle Brake - .223 Cal 1/2 -28 in
Just like the muzzle brake that came with your suppressor, DO NOT USE A CRUSH WASHER with the installation of this muzzle brake. This muzzle brake has been supplied with 5 shims so you can properly time the muzzle brake for proper orientation. Included are three thicker shims and two thinner shims to fine tune the timing of the muzzle brake. The two relief ports are to be located on the top at the 12 o’clock position. It is strongly recommended to use a high strength or permanent thread locker such as the Red Loctite 262 (high temperature), Rocksett or equivalent (not included) on the threads of your barrel just before installing for a secure hold.
