The RPM DC-34150 Delta 34mm Cantilever Mount (brand part no. DC-34150) is built to cut weight and keep a clean profile, skipping the integrated bubble level found on RPM’s Bravo series for shooters who don’t need it. Ruffs Precision machines the Delta series from 6061-T6 aluminum with a 303 stainless steel cross bolt and nut and an integrated recoil lug that locks the mount against the rail under recoil, while an alignment lug keeps the cap and base registered during installation. The 1.50-inch height to the center of the ring/optic gives forward mounting clearance for a large-objective scope on an AR-platform rifle. Among our scope bases, the DC-34150 suits shooters who want the lightest cantilever mount in RPM’s lineup for a 34mm-tube optic.
