OTTER CREEK LABS INFINITY 7.62 - NO MOUNT - USED

This is a used Otter Creek Labs Infinity, a multi-caliber 7.62 suppressor built from DMLS 3D-printed Inconel 718. It covers 5.56 and 6mm through 6.5mm, 7mm, 7.62mm, and subsonic 300 Blackout, and uses interchangeable end caps to tune backpressure for the host. It comes with four end caps. No mount is included. The rear is threaded 1.375x24 HUB, so a HUB mount will need to be purchased separately, such as a Dead Air Direct Thread Insert, SilencerCo Bravo Direct Thread Mount, Dead Air KeyMo Adapter, SilencerCo Bravo ASR Mount, or Plan-B by Q.

INFINITY AND BEYOND

The Otter Creek Labs Infinity is built for durability, adaptability, and long-term performance. To reduce costs, it’s sold without a mount, instead featuring a universal 1.375×24 HUB-threaded system compatible with a wide range of mounts. Customers can select their preferred option, suiting their own specific use-case and preferences.  

Designed for lower back-pressure performance, the Infinity balances sound suppression and reduces gas blowback. Optimized for 7.62 bore but excelling with 5.56 rifles, it underwent two years of refinement across 100+ prototypes. Its four-chamber design ensures efficient gas flow and offers three included end caps to customize back pressure: the solid 5.56 cap for maximum suppression, the vented 7.62 cap for minimal back pressure, and the solid 7.62 cap for a balanced option. A vented 5.56 cap is available separately for niche needs.

Made from 3D-printed, heat-treated 718 Inconel, the Infinity is tough enough for extreme use, with no barrel length restrictions and high endurance for firing schedules. While slightly heavier than some suppressors, it prioritizes performance and reliability. The Infinity is a versatile, durable suppressor designed to meet the needs of any firearm or user preference.
