100mm Dovetail to Weaver Picatinny Rail — Extended Base for Air Rifles

Short rail adapters limit your optic placement options — especially on rifles where eye relief is critical. The 100mm Dovetail to Weaver Picatinny Rail provides an extended 100mm mounting surface, giving you the full range of scope positioning for perfect eye relief. Convert your 11mm dovetail air rifle or .22 to the Picatinny standard with room to spare for your optic and accessories.

Key Features

Extended 100mm Length: At 100mm (nearly 4 inches), this rail adapter provides double the mounting surface of standard adapters. Position your scope for perfect eye relief and still have room for a backup sight or magnifier.
11mm Dovetail to Weaver/Picatinny: The base clamps onto standard 11mm dovetail rails, and the top surface is a full Weaver/Picatinny rail — compatible with both Weaver rings and MIL-STD-1913 Picatinny accessories.
Multi-Point Locking: Four hardened steel grub screws engage the dovetail at multiple points, distributing recoil forces across the entire rail length. The screws are positioned for maximum mechanical advantage against both forward and rearward recoil.
Stop Pin: An integrated recoil stop pin engages the dovetail factory stop hole, providing additional resistance against the bidirectional recoil of spring-piston air rifles.
Beveled Edges: All edges are beveled and deburred — no sharp corners to cut scope ring straps, slings, or hands during handling and transport.
