Modular designs in a 9mm caliber suppressor may not be revolutionary but creating one that works this well is nothing short of brilliant. The Obsidian has everything you could possibly want in a pistol silencer. 7.8" in the full configuration and 4.85" in the short or K Configuration combined with replaceable endcaps. On paper, the Obsidian would appear to be comparable to other top end 9mm suppressors. Real world functionality can be very different that paper specs though and the Obsidian lives up to it's hype. Rest assured that the Rugged Obsidian is a top performer on both pistol and subgun platforms in any configuration. It's also perfect for subsonic .300blk!
While the Rugged Obsidian will work on SilencerCo or Griffin pistons, the indexing grooves in their competitors pistons will cause a slight increase in gas blowback to the shooter. Currently shipping with one 1/2x28 piston.
