Griffin Armament’s DUAL-LOK 7 AM in FDE is a printed 7.62mm suppressor built for low backpressure on a .308-class rifle (brand part no. GADL762FDEAM-W). Its core is additive manufactured in Griffin’s Nickel 625X superalloy and laser-welded to a machined rear, combined with 17-4 H900 stainless steel and 718 Inconel. The flash hider end cap vents gas around its perimeter to reduce system backpressure on a gas gun. Griffin reports a 33.4 dB reduction, measured at 132.0 dB on a 16-inch Troy .308. A DUAL-LOK EZ-Brake in 5/8×24 is included, and the can is full-auto rated.

Frequently Asked Questions
