The Sportsmatch 13mm 2 Piece 1" High Scope Mounts (model HTO8-13MM, also known as HT08C13MM) are precision-engineered in Great Britain to provide a highly secure and robust mounting solution for rifles featuring specialised 13mm dovetail rails. Manufactured from high-tensile, aircraft-grade aluminium, this two-piece mounting system is specifically designed to eliminate alignment issues and prevent scope slippage on heavy-recoiling firearms. Because certain classic and modern rimfire rifles and air rifles feature wider 13mm receiver grooves rather than standard 11mm rails, these mounts ensure a perfectly centred, flush fit without requiring adaptor plates.

Key Features:

• Specialised 13mm Rail Fitment: Engineered specifically for 13mm BSA-style dovetail rails, ensuring a centred and secure fit without damaging the receiver.
• High-Tensile Aluminium Construction: CNC machined from aircraft-grade aluminium for structural integrity and a light total weight of 111 grams for the pair.
• Recoil Resistance: Equipped with a retractable and removable "Easyfit" recoil arrestor pin to prevent scope creep on high-vibration spring-piston air rifles and rimfires.
• Double Screw Clamping: Features double hex screw clamps on both the rail and the top caps (four screws per ring) for maximum grip.
• Generous Objective Lens Clearance: High-profile design allows clearance for rifle scopes with an objective front lens diameter of up to 56mm on most rifles.

Specifications:

• Tube Diameter Compatibility: 1 inch (25.4 mm)
• Mount Profile (Dimension A): High (24 mm from the bottom of the clamp to the bottom of the scope tube)
• Total Height: 36.7 mm
• Width / Base Length (Dimension B): 21 mm
• Weight: 111 grams (supplied as a matched pair)
• Base Rail Compatibility: 13mm BSA-style dovetail rails only (not compatible with standard 11mm or 3/8" dovetails, Weaver, or Picatinny rails)
• Country of Manufacture: Great Britain

Who It's For:

This mounting system is specifically designed for Australian target shooters, hunters, and rimfire enthusiasts who own firearms with 13mm receiver rails. It is the primary mounting solution for owners of modern British-made BSA air rifles (including the BSA R-10, Gold Star, and Ultra), the CZ 452 American rimfire rifle, early Brno Model 1 and Model 2 rimfires, and vintage Weihrauch HW35 airguns. Australian shooters looking to mount a 1-inch tube scope with up to a 56mm objective lens on these specific European and British receivers will benefit from the precise alignment and slip-free performance these mounts provide.
