SPR Complete Upper
Ridgeline SPR Complete Uppers are semi-custom built barreled receivers designed to enhance the accuracy and precision capability of your current AR platform. Our upper receivers are hand selected and trued before being fitted and assembled using the same single point cut barrels found in our full SPR build. All bolts are checked for proper headspacing and bolt carriers are staked and checked to insure gas tube/key alignment.
Barrel length and profile options are either 14.5", 16” SDM-L profile with an intermediate gas systems or 18''/20" SDM profiles, with full length rifle gas systems. Our Complete Uppers utilize the Geissele Super Modular Rails of your choice and are fitted with the Geissele Airborne or Super charging handle. The barrels are threaded for 1/2-28 and come with a Surefire muzzle brake or flash hider of your choosing.
