Griffin Armament Makes some of the finest Suppressors and Suppressor Parts on the Market Today

Griffin Armament was founded by two brothers, both combat veterans from Operation Iraqi Freedom. Their time in service left them both with hearing loss which drives them to manufacture suppressors to protect the hearing of fellow shooters. Because of Griffin Armament's knowledge in manufacturing, design, and understanding of suppressor applications, this has allowed the creations of industry leading suppressors and firearm solutions.

Manufacturer's Note:
Use of the CAM-LOK system with a fixed spacer on a fixed barrel firearm will cause damage to the suppressor. This is for use on handguns with tilt barrel pistols only such as Glock, HK, SIG, 1911, S&W M&P....etc. A fixed firearm would be a 9mm carbine (PCC), a bolt action, etc.
