The Otter Creek Labs Infinity is a 7.62 suppressor built to be the last rifle can you buy. It is printed from 718 Inconel and heat treated, with machined H900 17-4 stainless end caps, and it has no barrel length or firing schedule limits on magazine-fed guns. The name comes from the adjustability: three end caps ship in the box so you can set the back pressure for whatever host it lands on, from a bolt gun to an over-gassed AR or AK.
Inside, four chambers do the work. The first vents gas straight off the muzzle, the second holds it, the third blends the bore gas and the held gas, and the fourth is a high-flow zone that moves gas down the tube wall. A solid end cap holds that last chamber for maximum suppression; the vented cap opens it for the lowest back pressure. OCL spent close to two years and over 100 prototypes tuning it so that it performs on 5.56 as well as it does on 7.62. Made in London, Kentucky, with a lifetime warranty.
Why it stands out
- Three end caps included: solid 5.56 (quietest on 5.56), solid 7.62 (the all-rounder), vented 7.62 (lowest back pressure for MCX, SCAR, AR-10, AK and over-gassed ARs)
- DMLS-printed, heat-treated 718 Inconel; no barrel length or firing schedule limits on mag-fed guns
- Belt-fed capable: 300-round strings on 5.56, 200 on 7.62 with the vented cap
- Industry-standard 1.375x24 HUB rear thread: run any HUB mount you like
- Lifetime warranty

Compatibility
No mount is included. OCL surveyed its customers and most never use the direct-thread mount that comes with a can, so the Infinity ships without one to keep the price down. Pick any 1.375x24 HUB mount: our Direct Thread Adapter for direct thread, or the HUB quick-detach, 3-lug or booster system you already run. A vented 5.56 end cap is sold separately for the one niche between the solid 5.56 and vented 7.62 settings.
