Sons Of Liberty Gun Works L89 13.9 CHF HUXWRX 556 QD XL Semi Complete Upper

L89 Complete Upper Half, 13.9″ 5.56 Cold Hammer Forged Barrel, 13.9″ L89 Rail, P/W Huxwrx XL QD Flash Hider (NO BCG or CH)

The SOLGW V2 CHF  profile was designed with our customers’ needs in mind, delivering increased accuracy while balancing suppressed handling and performance.

With the significantly increased chamber support, our barrels are better suited for modern configurations where lights, lasers and suppressors all add to a commonly muzzle heavy carbine.

The transfer of material to the rear of the barrel helps to offset the weight of accessories, and stiffens the barrel at the same time – reducing POI shifts between suppressed and unsuppressed use. The gas journal length has been shortened as well to optimized weight distribution, so please note that fixed front sight bases will not fit on this barrel, only low profile gas blocks.

Our V2 CHF barrels remain appropriately gassed for use with or without a suppressor of your choosing.  This Cold Hammer Forged version is a good match for shooters who frequently get their carbines hot, and are looking for a highly durable barrel.

This Upper set is finished with a HUXWRX Flash Hider-QD 556 XL.

The Flash Hider-QD 556 XL is designed to mitigate flash when unsuppressed.
Flash Hider-QD 556 is compatible with HX-QD series (556k, 556, 762, 762 Ti and Magnum Ti) and FLOW series (556k and 762 Ti) suppressors. This flash hider is only compatible with VENTUM series suppressors when combined with the HUX HUB Adapter.

  • Compatible with HX-QD 556k, 556,
  • 1/2X28 TPI
  • Will bring a 13.7″ barrel to 16″ OAL


The Flash Hider-QD is designed to mitigate flash with unsuppressed. NOTE: Larger caliber mounts are NOT compatible with smaller caliber suppressors. Smaller caliber mounts ARE compatible with larger caliber suppressors.
