Talley BERGARA PREMIER 30MM MED EXT FRNT 20 MOA 8-40 SCREWS MOUNT 748X700LM

One-piece construction blends the ring and base into a single unit. Eliminating the ring/base joint not only keeps weight to a minimum, it provides a stronger mount. Each ring cap is 5⁄8'' wide, with four, TORX screws, to keep large scopes from slipping or shifting. Designed by Mel Forbes of New Ultralight Arms. Manufacturer Part Number: 748X700LM
