Description

Griffin Armament GP5 Features The Griffin Armament GP5 is a lightweight 5.56 suppressor engineered for general purpose use with a strong emphasis on durability performance and affordability. Built entirely from 17-4 stainless steel and utilizing patented baffle technology it delivers consistent sound reduction while remaining rugged enough for demanding training and hard-use rifle setups. With full auto rating and no barrel restrictions listed the GP5 is designed to handle intensive firing schedules while maintaining long term reliability. A 1/2x28 direct thread mount provides a simple industry standard attachment method for most 5.56 barrels and the suppressor can be pinned on barrels as short as 10.5 inches for compact build configurations. Front and rear 3/4 inch wrench flats support easy installation and removal including setups where rail integration is a consideration.
