OCL Infinity 556K

The Otter Creek Labs Infinity 556K takes the proven DNA of the full-size Infinity 762 and packs it into a shorter, lighter 5.56-focused suppressor built for hard-use rifles. After the success of its bigger sibling, OCL brought the same versatile, low-back-pressure concept to a compact K-can designed to run across AR-15s, AK-style hosts, bolt guns, SBRs, and full-size rifles without turning your setup into a gas-powered face sauna.

Built from advanced Haynes 282 alloy using additive manufacturing, the Infinity 556K is made to handle demanding firing schedules while keeping performance consistent across a wide range of barrel lengths and platforms. It is compatible with 5.56 NATO and 6mm calibers, offering reduced flash, solid sound suppression, and a shooter-friendly gas profile in a compact package.

The real party trick is the interchangeable end cap system. The Infinity 556K ships with a medium back pressure end cap installed, giving most shooters a balanced starting point right out of the box. Optional low and high back pressure end caps are available separately, letting you tune the suppressor around your host, ammo, and preferred shooting feel. More gas, less gas, somewhere in the middle, you get to pick your flavor.
