The Hawke 25mm Extension Ring 1" 2-Piece Weaver High (Model: 22124) is a specialised cantilever optic mounting system engineered to adjust eye relief on rifles with restrictive rail spacing or short receiver rails. Built from high-grade aluminium alloy with a matte black anodised finish, this 2-piece set features a 1-inch offset extension profile that allows shooters to position a riflescope further forward or rearward. The High profile design delivers 50 mm (2.0 inches) of height clearance to accommodate scopes with large objective lenses while clearing wide erector saddles, parallax side-wheels, and illumination modules on standard Weaver and MIL-STD-1913 Picatinny rails.

Key Features

• 1-Inch Cantilever Extension: Provides a 1-inch forward or rearward offset to optimise eye relief on short-action rifles and compact rail setups.
• High Profile Clearance: Measures 50 mm (2.0 inches) in total height to accommodate standard and large objective lenses over rifle barrels.
• Scope Tube Protection: Features internal cushion tape and rounded, bevelled edges to prevent marking, pinching, and scoring on 1-inch (25.4 mm) scope tubes under torque.
• Double-Hex Recoil Retention: Utilises double-hex top cap clamping screws (3 mm hex drive, M4 × 0.7 thread) and a crossbar rail interface (3 mm hex drive, M3.5 × 0.6 thread) to hold zero under recoil.
• Lightweight Construction: Weighs 71 g (2.5 oz) per set to minimise overall weight additions to the firearm.

Who is the Hawke Reach Forward Mount Weaver 1" for?

• Target shooters adjusting eye relief on short-action rifles — The 1-inch offset extension profile of this extension scope ring mount allows precise forward or rearward placement of 25.4 mm (1-inch) optics to achieve correct eye relief on compact rail platforms without adding excessive bulk, weighing just 71 g (2.5 oz).
• Pest control hunters mounting long scopes on Weaver rails — The 50 mm (2.0 inches) High profile configuration of this extension ring set provides sufficient vertical clearance over the barrel for large objective lenses while bridging the span between short rail sections.

Less suitable for: Rifles featuring 9–11 mm or 3/8" grooved receivers where a dovetail-specific mounting ring is required; optics with 30 mm or 34 mm maintubes which require matching 30 mm or larger scope rings; or applications requiring more than 1" of reach, where a 2-inch extension model or single-piece cantilever mount is better suited.
