It features a modular baffle system that allows users to configure overall length and weight to suit their firearm setup. The suppressor ships with a 1/2-28 piston and booster assembly, making it compatible with common threaded 9mm pistol barrels out of the box.

Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.
