The LaRue SPR/M4 QD Mount 1.93″ is designed for shooters who need increased optic height to clear top-mounted accessories such as lasers illuminators or backup iron sights—without sacrificing stability or return-to-zero performance. Placing the optic centerline 1.93 inches above the rail this mount provides a more upright head position and improved situational awareness making it ideal for modern carbines LPVO setups and night-vision-adjacent configurations. The extended cantilever positions the optic forward over the handguard eliminating the need to bridge between the receiver and rail. The SPR/M4 mount features LaRue’s patented backbone design that rigidly connects the split vertical rings. This increases strength repeatability and alignment accuracy while eliminating the need for lapping. Precision-machined from bar-stock aluminum and finished with a matte black anodizing the mount is built to withstand hard use in demanding environments. Equipped with LaRue’s adjustable QD Speed Levers the SPR/M4 QD Mount delivers true return to zero allowing the optic to be removed and reinstalled without loss of accuracy.
