OSS Suppressors, radically innovative.

My first real experience with OSS Suppressors involved one helluva meal and get together after a long day of walking the 2017 SHOT show floor. I had been invited to a party hosted by OSS Suppressors. I remember walking in the door and was handed a cold beer and a real bar-b-que sandwich, and I thought to myself “these are my people”. We talked about guns, good bourbon, guns, and silencers. Yes, I mentioned guns twice because we talked about guns a lot. I got to meet better than a dozen of the OSS crowd and they were all good people. At the risk of maybe breaking protocol, I began to inquire about a silencer to test. I was immediately introduced to the marketing guy, and another beer, and we talked business for a few. It was a great time, and I secured a ride back to my hotel.

It was a couple of months ago the Elite 7.62, EL762 test silencer made it’s way to my house and I immediately pressed it into service. By the time the video was done I had well over 400 rounds through the can. With the flow through technology I experienced no malfunctions or point of aim, point of impact shift. While that may not seem like a big deal, it really is. The EL 762 does utilize a proprietary QD mount that acts as a flash hider when you run your rifle without the silencer. The EL 762 is rated up to and including the .300 Winchester Magnum.

The OSS line does not utilize a baffle stack but a turbine style inside that slows down, redirects, and suppresses the report and muzzle flash. With their proprietary flow through technology bolt overspeed becomes a non issue. While the standard baffle design silencer can add approximately 30% of bolt speed due to so much gas being redirected back, the OSS design adds about 3%. The added benefit of the OSS design is the gun will run cooler with less fouling. So, if you have been relying on an adjustable gas system on your rifle to negate malfunctions, that can be omitted when you run the OSS can. One thing to keep in mind if your 300 Blackout rifle relies on silencer back-pressure to operate you may run into some issues. That being said, a correctly set up 300 BLK rifle should cycle quality subs and supers with or without a can.

We ran the OSS can on a Barnes Precision Machine LR-10 .308 to 400 yards without a change in accuracy, a BPM 16″ Patrolman Carbine in 300 Blackout to a 100 yards, a BPM AR-15 11.5″ and 7.5″ to twenty five yards with no change in reliability or accuracy, even with extended full auto fire. During all of this the silencer held up very well. According to my decibel meter, which measures the entire sound wave, not the peak sound, the .308 fired from the BPM LR-10 was in the 108 db range while the .300 Blackout was in the 85 db range. Both considered hearing safe for a brief impulse sound.

OSS Suppressors has changed the silencer market with some innovative technology and machining to a silencer that will hold up to some heavy use while not affecting reliability on the weapon system. For the EL line there was no barrel length restriction, even for full auto fire, which is very rare for what is available currently.
