The Otter Creek Labs Milkman 9×19 titanium suppressor in black is a purpose-built 9mm can for rifles, PCCs and subguns. It is DMLS 3D printed from Grade 5 titanium at about 8.8 ounces. Its low back pressure design keeps gas out of the shooter’s face, which blowback AR9 shooters and lefties will notice. It uses the HUB 1.375×24 interface, so most 3-lug, direct-thread and QD suppressor mounts fit. Otter Creek Labs designed it for shoulder-fired 9mm platforms.

Frequently Asked Questions
