At 10.5 pounds the upper carries the heft needed to stabilize the platform for consistent long range accuracy. The flat top upper design accepts a wide range of optics for precision work at extended distances. Built for shooters who already run an AR-10 pattern lower and want serious reach the Seekins Precision SP10 is ready to bolt on and head to the range.
