Otter Creek was determined to create a suppressor that could last forever-something you could use for a lifetime, pass down to your grandchildren, and keep going strong. This resulted in the Infinity, a .30-caliber suppressor designed to perform just as well with .223/5.56 rounds as it does with the larger 7.62 calibers. They spent two years testing over 100 prototypes to develop this adaptable and durable suppressor. It comes with three end caps that allow you to adjust back pressure and flow rate based on the caliber you're using. The Infinity is made entirely from DMLS 3D-printed and heat-treated 718 Inconel, with the interchangeable end caps machined from 17-4 stainless steel. If you're looking for a do-it-all, hard-use suppressor that can handle the most brutal firing schedules, look no further. Otter Creek Arms Llc INF762FDE Infinity 7.62mm Flat Dark Earth
