OSS Suppressors took the traditional baffle style suppressors and threw them out the window. With their line of suppressors, they use a flow-through design that more resembles a turbine to slow down hot expanding gasses over a longer period of time than baffles do. This offers many benefits like less gas blowback into the action, a cooler running suppressor, and a longer service life all while still reducing decibels levels dramatically. The Helix-QD 762 is full auto rated up to 5.56 and is capable of being used on rifles up to 300 Winchester Magnum. The internals are made from a mix of 17-4 PH Stainless Steel and Grade 5 Titanium while the external sleeve is made from 17-4 PH Stainless Steel, black Cerakote finished, and fully welded to the internal structure. If you are looking for the suppressor of the future, you can't go wrong with the OSS Helix-QD 7.62.
