DefenseReview (DR) first covered OSS Suppressors in 2014, after we got to see their internals at SOFIC 2014. Actually, that’s not exactly true. We really first got to see them in 2012 at NDIA Joint Armaments Conference 2012, when they were still called Bravo 18. Well, OSS Suppressors has come a long way since then. They now have their Helix QD line of suppressors that are much shorter in length, and faster to put on and take off. They even now have a 7.62mm NATO (7.62x51mm NATO) belt-fed machine gun-rated suppressor called the HX-QD 762 MG, as well as titanium suppressors (HX-QD 762 TI and HX-QD Magnum TI. They’ve also got two slick little 5.56mm NATO cans (muzzle cans) called the HX-QD 556 and HX-QD 556K, both of which are full-auto rated.
Of course, all of the OSS Helix QD cans utilizes the company’s proprietary “Flow-Through” technology which creates very low levels of back pressure, for increased longevity/service life. The HX-QD 762 MG belt-fed machine gun can is particularly interesting to DR, as a rugged and reliable belt-fed MG can is more difficult to engineer, for obvious reasons (i.e., much higher heat and stress levels).
Defense Review has never actually run any of the OSS Suppressors Helix QD cans at the range, but we hope to remedy that at some point in the not-too-distant future. In the meantime, you can see all of them in DR’s video below, which we shot at SHOT Show 2019. Unfortunately, we didn’t photograph the internals of any of the new cans like we did on the old ones, so we’ll try to obtain some photos of them. We’re interested in the design changes that OSS made to shorten the cans, and get them machine gun-rated.
