Description

Please note: We strive to provide the most accurate photographs of our product wherever possible. Due to availability limitations and supply chain constraints, slight variations of the handguard of this upper assembly may occur in the aesthetics of the skeletonizations in between the M-Lok sections.

For the longrange shooter who demands a do-it-all AR with a .30-cal. This 300 Blackout build kit provides a lightweight rifle that can shoot suppressed or un-suppressed with supers and subs all day (and night, for the hogs). With a 16″ barrel forged from 4150 CMV with a 1:8 twist providing optimal velocity and stability for all grains and loads, this rifle kit yields MOA accuracy in any configuration.
