OSS Suppressors has just released its latest addition to its line of Helix Suppressors – the HX-QD 556 Ti. The HX-QD 556 Ti is a lightweight titanium suppressor that cuts an additional 4oz of weight from its 17-4 stainless steel brother. OSS claims that unlike other Titanium suppressors that have a shorter lifespan, the HX-QD 556 Ti has a durability that delivers in excess of 40,000 rounds.

OSS Launches the New Helix HX-QD 556 Ti Lightweight Rifle Suppressor

• Weight: 13.1 oz
• Length: 6.67 in
• Diameter: 1.60 in
• Coating: C-Series Cerakote Matte Black (Other color options available)
• Construction: Grade 5/Grade 9 Titanium, 17-4 Stainless Steel
• Muzzle Accessory: Either Flash Hider QD or Muzzle Brake QD Available

The HX-QD 556 Ti is rated for full-auto fire with 5.56 rifles and no minium barrel restrictions. The New Flash Cap eliminates virtually all-flash and combined with OSS’s patented and proven Flow-through and Torque lock technology makes for superior accuracy and reliability.

Dipping into the white paper provided on the OSS website there are a few other interesting pieces we can see about the Ti release of the suppressor. The suppressor is capable of delivering a Sound Pressure Level of 140 dB at the shooter’s ear per the TOP 3-2-045 Testing Methodology. This result, however, is highly dependent on the weapon system used, barrel length ammunition, and environment.

The white paper also goes on to list a maximum external temperature for the suppressor of 1238 degrees Fahrenheit. This was tested using a reliability stress test which consists of 8 magazines shot in succession after the system has cooled to a temperature of 120 degrees Fahrenheit using forced air before proceeding to the next magazine. During this test, the firearm is not cleaned or maintained until after the test is complete.
