The Otter Creek Labs Infinity 7.62 suppressor in Flat Dark Earth is a multi-caliber can with a 7.62 bore, built for shooters who want durability and one suppressor for several rifles. Its body is DMLS 3D-printed Inconel with a low-backpressure design that vents gas forward to reduce blowback on semi-auto rifles. It handles cartridges from 5.56 through 7.62mm, including 6.5mm and subsonic 300 Blackout. At 6.5 inches and 20 ounces without a mount it adds suppression without dragging the rifle down. A HUB 1.375×24 rear thread makes it compatible with popular direct-thread and quick-detach mounts.
