[SHOT 2018] OSS Suppressors – The New HELIX-QD Mounting System

    HELIX-QD

    In the past, OSS Suppressors has taken their fair share of heat and pressure (see that) for their unique designs, multi-generation models, price points and mounting systems. And honestly I have contributed to the criticism. Until recently, previous models featured two module sections and over-barrel mounts that required specific rifle setups. However, I spent a good amount of time with the OSS crew today talking about their new HELIX-QD mounting system and OSS’s path going forward, and I think they have a new fan.

    First up, the HELIX-QD mount is a return to a more traditional threaded muzzle brake with a tapered bearing surface to keep expanding gases where they belong. The brake itself threads on to the barrel with standard threads, but the silencer utilizes left hand threads to prevent it from twisting off under fire. The added benefit is that the reverse threads won’t unloosen the brake when removing the silencer. The mount also tightens up nicely and stays firmly in place. I think OSS has a winner in the HELIX-QD – simple and solid.

    The new silencers come in three versions: a 5.56K, 7.62 and the Ti Magnum, all of which now sport a round outer tube instead of the hexagonal sleeve on previous versions. The change in form factor reduces both cost and manufacturing complexity.

    Weight 15.5 oz
    Length 5.7 in
    Diameter 1.6 in

    HX-QD 762

    Weight 19.6 oz
    Length 7.2 in
    Diameter 1.6 in

    HX-QD MAGNUM TI

    Weight 18.3 oz
    Length 8.73 in
    Diameter 1.6 in

    As for the company itself, I got a real positive vibe from the OSS team. They openly talked about having some miss steps with previous employees/management during product development. The new rifle suppressors are here to stay for the foreseeable future, avoiding generation creep, while OSS engineers continue work on a rimfire and pistol line of silencers due out in the near future.

    I can see myself owning an OSS Suppressor, which is something I haven’t said in the past.

    Details, specifications and the official press release can be found below.

    OSS Introduces New HELIX-QD Suppressor Line

    Millcreek UT – OSS Suppressors LLC is proud to announce the new HELIX-QD suppressor line in 5.56k, 7.62 and Magnum configurations.

    “Our new Helix-QD (Quick Disconnect) line is the culmination of hard work that began two years ago when OSS Suppressors acquired Operators Suppressor Systems,” said John Spurrier, CEO of OSS Suppressors.  “Armed with insights and feedback from customers, dealers, OEMs and military partners, our design and engineering team implemented a development process that intensively analyzed and tested new designs to extremes. The result is an evolution of OSS’s Flow-Through™ technology in this new one-piece design” he said.  “We’re excited by the reaction we’re getting from dealers and partners for these new quieter, shorter, lighter and stronger suppressors.”

    • HX-QD 556k: a short, extremely durable suppressor. It delivers sub-140 dB performance, is full-auto rated and easily passes the USSOCOM Reliability Stress Test – it’s designed and built for abuse.  MSRP is $899.
    • HX-QD 762: a strong “utility player” suppressor. With its design and development heavily influenced by the U.S. Army CSASS requirements, the HX-QD 762 delivers 136-139 dB performance, is full-auto rated up to 7.62, and is cross-platform compatible from 5.56 up to .300 WM — there’s no other suppressor like it on the market. MSRP is $999.
    • HX-QD Magnum Ti: a short, lightweight and durable suppressor for large bore rifles – ideal for most .30 caliber platforms. With a fully welded Grade 5 titanium body and heat treated 17-4 stainless steel and Grade 5 titanium internals, the HX-QD Magnum Ti is full-auto rated for 5.56, and delivers hearing safe suppression from 5.56 (sub-133 dB) to .338 (sub-139 dB) — no other .338 suppressor is this versatile.  MSRP is $1599.

     “What’s most impressive about this new product line is how our engineers built the unmatched benefits of Flow-Through into a simpler one-piece design and improved or maintained the benefits,” said Chris Estadt, VP of Marketing and Sales. “For example, the new tool-less HX-QD Torque Lock System (TLS) – maybe the most advanced yet simple mounting system in the market – uses the rotational pressure from gasses exiting the suppressor to keep it snug on the muzzle device. It can’t shoot loose and you don’t need a complicated mechanical device…that will ultimately fail.” he said. “How snug? Testers have said detaching the HX-QD can is like opening a pickle jar.”

    OSS’s disciplined product development process and simple one-piece design will accelerate continued innovation and new products – including rimfire and handgun suppressors – for dealers and their customers.
