The Otter Creek Infinity 556K Suppressor 5.56 5.5" HUB/Bravo/1.375x24 is a compact, hard-use rifle suppressor built from 3D printed Haynes 282, a high-temperature superalloy chosen for durability and long service life. Its short 5.5" length and 14.5 oz weight keep rifles nimble while delivering impressive sound reduction and low flash signature.

This model uses an adjustable end cap system that lets shooters tune back pressure for different hosts, from bolt guns to over-gassed AR or AK platforms. It ships with a medium back pressure vented end cap, with additional caps available separately, and features a HUB 1.375x24 rear pattern for broad mount compatibility. Ideal for range use, training, and general rifle shooting, the Infinity 556K reflects Otter Creek’s reputation for robust, well-engineered suppressors that are built to last.
