The Otter Creek Labs Infinity 556K is a compact 5.56 suppressor engineered for versatility, durability, and reduced back pressure across a wide range of rifle platforms. Built from advanced Haynes 282 alloy using additive manufacturing, the Infinity 556K is designed to withstand demanding firing schedules while maintaining consistent performance on both short and long-barreled rifles. Compatible with 5.56 NATO and 6mm calibers, this suppressor delivers low flash signature, balanced sound suppression, and adaptable tuning for various firearm setups.
A standout feature of the Infinity 556K is its interchangeable end cap system, allowing shooters to fine-tune back pressure levels based on their rifle configuration and shooting preferences. Whether paired with a bolt-action rifle, AR-15, or AK-style platform, the suppressor can be optimized for reliability and shooting comfort. The suppressor ships with a medium back pressure end cap, while optional low and high back pressure end caps are available separately.
