The Leapers Dovetail-to-Picatinny/Weaver Cantilever Adapter Mount (brand part no. MNTDTW145) converts a 9mm to 11mm airgun or shotgun dovetail rail into a full-length 5.7-inch Picatinny top rail with 14 slots, opening up eye relief adjustment and mounting options that a factory dovetail cannot support. Leapers machines the adapter from aircraft aluminum and finishes it with a matte black hard-coat anodize, then includes four high-strength screws along with adjustable, recoil-resistant stop pins to keep it locked at zero under bidirectional recoil. It slides on and fits both flat and rounded dovetail receivers.
