Ruffs Precision Rail Cap Features Ruffs Precision builds the Rail Cap to be compact and lightweight while remaining compatible with as many optic and accessory combinations as possible. This high profile diving board style cap replaces the factory top section on compatible RPM mounts opening up usable rail space for a secondary red dot or laser rangefinder above a primary magnified scope. Machined from aluminum and measuring 4.9 inches long and 2.6 inches wide the cap keeps its added rail section proportionate to the mount beneath it. At roughly 0.13 pounds it adds almost no weight to an already assembled optic setup. Because the Rail Cap fits every existing RPM product including the full CLR series of rings and both the Bravo and Delta cantilever lines shooters gain secondary mounting space without replacing their primary optic mount. The original screws included with the mount s initial purchase are the correct fasteners for installing this cap so no extra hardware is needed. Finished in Flat Dark Earth the cap matches tan coyote and FDE Cerakote rifle builds for a cohesive appearance. This Ruffs Precision Rail Cap in Flat Dark Earth is available for sale at GrabAGun for shooters outfitting a desert toned precision rifle with a secondary optic.
