Otter Creek Labs Universe-36 Features The Otter Creek Labs Universe-36 is built around an adjustable end cap system that lets the shooter switch between low back pressure and high back pressure configurations depending on caliber and host gun. This means the same can works on a suppressed 9mm handgun a full auto 5.56 SBR or a hard-hitting .338 Lapua rig chambered in .36 Caliber or smaller with end caps swapped using nothing more than a socket or adjustable wrench. No proprietary tools are needed which keeps the suppressor field serviceable and easy to maintain between range sessions. The universal HUB and 1.375x24 thread interface means any mount QD system booster or 3 lug adapter already in the shooter s collection bolts right on. Constructed from Inconel using DMLS printing the Universe-36 is engineered to withstand full-auto fire belt-fed cyclic rates and sustained high round counts without breaking down. At just 7 inches long and 14 ounces it adds minimal length and weight to a host firearm while still delivering serious sound suppression across a huge range of calibers. The matte Flat Dark Earth finish matches modern builds without drawing attention and the suppressor ships with a 9mm low back pressure end cap already installed and ready to run. Additional end caps for 7.62 and 5.56 in both low and high back pressure configurations are sold separately for shooters who want to dial in performance on every gun they own.
