Designed to be the King of the hill when it comes to suppressing and harnessing the recoil of those big, long-range boomers. The ULTIMUS, just like its two siblings, is 100% Titanium and features the same unique PATENT PENDING design that turns the entire suppressor into an expansion chamber, which yields substantially less back pressure and recoil. Available in TWO DIFFERENT CALIBERS and FIVE LENGTHS to make those long shots less punishing.
