SBR8 Complete Upper

The SBR8 is ideal for quiet and quick sport shooting, short-range competitions, and home defense. Seekins Precision’s Integrated Rail Mounting technology (iRMT) uppers integrate the rail mounting points into the upper receiver. This retains the stiffness while allowing the rails to be completely modular. Designed to be used with a suppressor (not included).
