16-Inch Suppressor Ready Barrel

This upper is equipped with a 16-inch barrel that is threaded for suppressor use. The suppressor-ready configuration allows users to easily mount a wide variety of suppressors without the need for additional adapters in most cases. The 16-inch barrel length provides an excellent balance between velocity, maneuverability, and overall rifle length, making it ideal for both home defense and general-purpose builds. Faxon barrels are known for their accuracy and durability, with proper headspacing and consistent bore dimensions.

13-Inch Handguard

The handguard is designed to allow for a comfortable and stable grip while maintaining a slim profile. Its free-float design helps improve accuracy by eliminating contact with the barrel, allowing the barrel to vibrate consistently during firing.
