The Otter Creek Labs Universe-36 is the one-suppressor-for-everything can: anything with a bullet of .36 caliber or less, from 22 LR and 5.56 through 9mm, 300 BLK, 30-30 and 308, all the way up to 338 Lapua. It is printed from Inconel with the same tough DNA as the Infinity, so forced-reset triggers, full auto and belt-feds are all fine. This is the Black Cerakote version.
An end-cap system lets you tune back pressure for the gun and caliber: it ships with a 9mm low back-pressure (vented) cap installed, and 9mm high, 7.62 low/high and 5.56 low/high caps are sold separately. Caps change with a socket or an adjustable wrench, no proprietary tool. The 1.375x24 HUB rear thread takes any mount, booster or 3-lug, so it moves between a 9mm handgun and a magnum bolt gun with a mount swap. Made in London, Kentucky, with a lifetime warranty.
