Ruffs Precision RPM 34-LRC 34mm Low Rail Cap - Black

The Ruffs Precision RPM 34-LRC is a 34mm low rail cap - commonly referred to as a "diving board" - that replaces the standard top cap on Ruff's Precision Manufacturing scope ring and cantilever mounts. Machined from aluminum and finished in black, the cap adds a short Picatinny rail surface forward of the main scope ring, providing a dedicated mounting point for a rail-mounted laser rangefinder or a secondary red dot / aiming device alongside your magnified optic.

This rail cap is a direct, drop-in replacement that fits all existing RPM products, including the CLR series rings and the Bravo and Delta cantilever mounts. Using the original cap screws from your existing RPM ring or cantilever, this simple swap converts the mount into a low-profile accessory rail without altering the optic's position or eye relief. Weighing just 0.12 lb and measuring 4.9" long by 2" tall, the low cap keeps added weight and bulk to a minimum while still delivering usable rail space for accessories.
