The Rugged Suppressors Fixed Mount M18x1 is a stand-alone mounting accessory for fixed-barrel hosts (brand part no. OF004). Rugged Suppressors designed it for carbine and subgun platforms, where it replaces the booster system in the Obsidian 45 and Obsidian 9. This version is cut for M18x1 barrel threads. On a fixed-barrel host the mount takes the place of the booster system on the suppressor. It is not used together with the 3 Lug Mount or the Fixed Barrel Spacer, so pick one configuration for the host.
