YHM developed this Universal Rifle Suppressor Mount to convert existing suppressors from other manufacturers to utilize your barrel threading as a direct mounting system. Due to its simplistic design there is virtually no way to incorrectly install the suppressor and risk the chance of it coming loose yet it provides easy removal. - To install simply remove your existing mount mechanism from your suppressor and thread on our Universal Rifle Suppressor Mount using a 3/4 open end wrench. Then simply thread the now two-piece suppressor onto your barrel. - 17-4PH Heat Treated Material - Melonite QPQ Finish - 1-3/8-24 Mount Thread Pitch - Weight: 1.696 oz
