Description
The Diamondback Ventra 5.56 NATO suppressor in FDE is a short, full-auto rated rifle can rated by Diamondback for 5.56x45mm, finished in Cerakote Flat Dark Earth (Diamondback part no. DBS-556IFDE). It adds just 5.088 inches to the muzzle, which keeps an AR-15 quick to handle for training, home defense or competition. The Inconel 718 core and 17-4 stainless steel endcap are built for heat and long service life, and asymmetric baffle geometry balances suppression with backpressure for an even sound and controlled flash. Pressure Venting Technology moves gas away from the shooter’s face. A 1/2-28 direct thread mount ships with it, and the HUB compatible design lets you move it to other hosts with the matching mount.
