Otter Creek Labs, Infinity, Rifle Suppressor, 7.62MM, Inconel Construction

The Otter Creek Labs Infinity is a versatile, durable 7.62mm (.30 caliber) rifle suppressor designed for multi-caliber use and hard-use applications. It's Otter Creek Labs' first 3D-printed model, emphasizing longevity (marketed as something you can "pass down to your grandchildren"), tunable back pressure, and reduced gas blowback compared to traditional designs.
