The Otter Creek Labs Infinity Suppressor 556K 5.56 NATO FDE is a compact, hard-use rifle suppressor engineered around a fully printed Haynes 282 construction. Measuring 5.5 inches in length, it delivers impressive sound and flash reduction while keeping overall rifle length and weight to a minimum. The Infinity 556K stands out with its adjustable end cap system, allowing shooters to fine-tune back pressure for different hosts without changing the core suppressor body.

This model ships with the medium back pressure end cap installed, giving a balanced blend of gas control and reliability on most semi-auto rifles. Optional low and high back pressure caps (sold separately) let you optimize performance on everything from smooth-running bolt guns to heavily gassed AR or AK platforms. HUB compatibility ensures broad mounting options, though a mount is not included, so you can pair it with your preferred system. The Infinity 556K is well suited for range use, training, and general-purpose rifle shooting, reflecting Otter Creek Labs’ focus on innovation and practical, shooter-driven design.
