Features:

  • TORQUE LOCK®: HUXWRX Torque Lock is a patented, tool-less locking system that ensures the suppressor will stay securely mounted onto the HUXWRX QD muzzle device.
  • HEARING SAFE: The HUXWRX Test Rifles shall not exceed 140 dB ten-shot average sound pressure level at the shooter’s ear during barrel life.
  • FULL-AUTO RATED: HUXWRX suppressors' full-auto rating guarantees the suppressor passes the USSOCOM Reliability Stress Test.
  • CROSS-PLATFORM COMPATIBLE: HUXWRX QD suppressors can be used on a variety of calibers and rifle platforms.
  • PRECISION CERTIFIED: HUXWRX Suppressors are engineered and tested to meet the highest military accuracy specifications worldwide.
  • REPEATABLE & MINIMAL SHIFT: HUXWRX Suppressors are engineered so that the mounting interface is precise and consistent. The result is the repeatable and minimal point of impact (POI) shift that meets military specifications worldwide.
  • NO WEAPONS MODS: Modifications to the bolt, gas tube, buffer or recoil springs, and other timing modifications are unnecessary.
  • RECOIL MANAGEMENT: Bolt velocity increases vary between -2% to 5% depending on the weapon system, barrel length, and ammo types.
