Otter Creek Labs Infinity 556K Suppressor | 5.56 | 5.5″ | Haynes 282 | HUB/Bravo/1.375×24

The Otter Creek Labs Infinity 556K is a premium 5.56 suppressor engineered for shooters who refuse to compromise. Machined from Haynes 282 — the same high-performance superalloy trusted by aerospace engineers and metallurgists — this suppressor is built to outlast you, your kids, and your grandkids.

Adjustable Back Pressure System — The Real Difference Maker

What sets the Infinity 556K apart from the competition is its adjustable end cap system. By swapping between low, medium, and high back pressure end caps, you can fine-tune gas management to suit virtually any host firearm — from bolt-action rifles to heavily over-gassed AR and AK platforms. The suppressor ships with the medium back pressure end cap installed; low and high back pressure end caps are available for separate purchase.

Performance You Can Feel and Hear

The Infinity 556K delivers low back pressure without sacrificing sound suppression. Whether you’re running a full-length precision rifle or a short-barreled carbine, expect consistent, reliable performance. Low signature. Low flash. Full capability — regardless of barrel length.

Built on a Proven Legacy

Otter Creek Labs has built a reputation for producing suppressors that hold up under real-world use. The Infinity 7.62 has already proven itself over years in the field, and the Infinity 556K carries that same DNA forward. This is a suppressor designed not just to perform today, but to remain a trusted tool for decades to come.
