Q LLC The Fix Fixed Barrel Assembly 8.6 Blackout 16" 1:3 Twist Stainless Steel

The Q LLC The Fix Fixed Barrel Assembly is a precision-engineered replacement barrel for Q's The Fix rifle platform, chambered in 8.6 Blackout with a 16" overall length that clears the federal rifle minimum-length requirement.

Machined from high-strength 416R stainless steel with a bead blasted matte finish, this barrel is built around a fast 1:3" twist rate optimized to stabilize heavy supersonic and subsonic 8.6 Blackout projectiles.

The assembly ships as a complete unit with a headspaced barrel extension pre-installed, so swapping calibers or replacing a worn barrel on your Fix is a straightforward operation. Fitment note: this barrel assembly is engineered exclusively for the Q The Fix platform and is not compatible with AR-10 or Remington 700 actions.
