Primary Arms SLx 30mm Cantilever Scope Mount - 1.5 Inch

The Primary Arms SLx 30mm Cantilever Scope Mount is engineered to deliver rock-solid optic retention while keeping weight to a minimum. Designed for AR-style rifles, this mount positions your optic at an optimal 1.5-inch optical centerline, providing a comfortable and natural sight picture for modern shooting stances.

Constructed from 6061 aluminum and reinforced with steel hardware, the SLx mount uses an innovative three-bolt clamping system that distributes recoil forces evenly across the rail. This design generates over 6,500 pounds of clamping force, ensuring your optic remains secure under recoil, impact, and extended firing sessions.

Dual machined recoil lugs combined with three cross-bolt lugs prevent any forward or rearward movement, maintaining zero even in demanding conditions. Despite its strength, the SLx mount remains lightweight and compact, making it ideal for duty rifles, competition builds, and general-purpose carbines.

The SLx mount is also compatible with the Primary Arms SLx 30mm Top Cap Reflex Mount, allowing shooters to easily add an offset red dot for close-quarters transitions. Like all Primary Arms mounts, it is backed by a lifetime warranty.
