Features of STNGR HWK AR15/M4 M-Lok Free Float Handguard

  • Incredibly simple installation. The HWK, with its simple non-timing barrel nut, was engineered to be the easiest handguard to install on the market. Perfect for first time builders and seasoned gunsmiths alike. No hassle, no frustration, no previous experience required. Simple.
  • Locking anti-slide plate. The HWK solves a problem that plagues most rails on the market - handguard sliding. With their proprietary anti-slide plate that interfaces with a groove in the barrel nut, the HWK is locked to the upper - ensuring that it won't go anywhere.
  • Anti-rotation tabs. Forward sliding is a problem that's solved with the anti-slide plate, but what about lateral rotation? The HWK has built in anti-rotation tabs to prevent any kind of rotation. By combining the anti-slide plate and anti-rotation tabs, the result is a rock solid fit - no matter how hard you run it.
  • Lightweight, increased ventilation. Aggressive machining cuts throughout the rail serve 3 critical functions: 1) Significantly slash excess weight 2) Increase ventilation to cool both your handguard and barrel 3) Steep angles prevent fingers from sliding into grooves.
