Manufactured to ultra-tight tolerances under strict quality controls, the Scalarworks® LEAP/02 Aimpoint® Pro/CompM4 QD Mount has completely redefined the standards for quality and reliability, consistently outperforming virtually all other mounting platforms currently on the market. High-strength 7075-T6 billet aluminum construction provides the ideal strength-to-weight ratio, capable of withstanding up to 1,500 lbs of force without twisting or cracking — all while maintaining a lightweight, streamlined profile. The highly efficient clamp design features an oversized hooded thru-hole to buttress the thumbscrew's shank, which is the maximum possible diameter to fit a Picatinny channel. A pair of hardened steel precision ground pins are press-fitted to the clamp and act as guides, guaranteeing precise operation and unprecedented rigidity. Proprietary ClickDrive® technology utilizes simple hand strength to secure the mount to the rail by using natural force from the built-in spring-loaded ball detent. This also allows the mount to hold true to zero under punishing recoil and provides a quick return to zero without any special tools or adjustments, guaranteed. Compatible with all flat-top rail-equipped long guns, including semi-auto and pump-action shotguns and some lever-action rifles. Convinced? Us, too. Order today!
