The Nightforce Rail Accessory Platform - Improved (RAP-i) is designed for mounting Laser Range Finders (LRFs) above the front ring of the riflescope. The skeletonized, truss-like design allows for superior rigidity and point of impact retention of LRFs. The RAP-i includes the MultiMount(TM) ring cap that allows the RAP-i to be mounted on the Nightforce UltraMount(TM), Unimount(TM), 4-screw Xtreme Duty(TM) rings, and 6-screw Xtreme Duty(TM) rings. RAP-i with MultiMount cap adds 3.9oz. Mfg: Nightforce
