Spine L

Purpose-built for shooters running forward-mounted optics, this full-length riser transforms your upper into a single, rigid mounting platform.

Machined from 6065 aluminum, this variant spans 16 inches of top rail, bridging the flat top receiver to the handguard. By mechanically tying both sections together, it eliminates deflection between components—delivering a significantly more stable optic interface and maintaining zero even when running weight further forward.

The 1.75” rise establishes a heads-up shooting position, improving situational awareness while doubling as an integrated cheek rest for consistent alignment shot-to-shot. The extended rail provides ample space for optics, magnifiers, or night vision support, while the integrated carry handle adds both function and control without unnecessary bulk.

This is not just a riser—it’s a structural upgrade to your platform.
