The Sportsmatch OP25C 1-Piece Scope Mount (also referred to as the Sportsmatch 3/8 1 Piece 1" Med Double Screw) is a high-precision, British-made mounting solution designed for optimal alignment and structural rigidity. CNC machined from aircraft-grade aluminum, this one-piece mount is engineered to withstand the heavy vibrations and unique bi-directional recoil forces generated by high-power spring-piston air rifles and rimfire platforms. By offering a continuous, rigid single-block design, the OP25C ensures superior zero retention and scope security under demanding shooting conditions.

Key Features:

• One-Piece Rigidity: Machined from a single block of aluminum, providing better alignment and structural strength than traditional two-piece ring sets to prevent scope movement.
• Double Screw Clamping System: Features double-screw clamps on both the individual ring caps and the base mount, ensuring an evenly distributed, secure grip on both the scope tube and the receiver rail.
• Removable Arrestor Pin: Includes an integrated, removable recoil stop pin that locks securely into the receiver holes to mitigate the sliding effects of recoil.
• High-Grade Materials: Constructed from premium aircraft-grade aluminum to offer high durability and corrosion resistance without adding unnecessary weight to your rifle setup.

Who It Is For:

The Sportsmatch OP25C is designed for Australian shooters utilizing spring-piston air rifles, pre-charged pneumatic (PCP) airguns, and .22 rimfire rifles. Because the 3/8 inch to 11 mm rail configuration is highly common on local rimfire and airgun receivers, this mount is a practical upgrade for agricultural pest control, small-game hunting, and competitive target shooting. It is particularly suited for shooters operating high-recoil spring airguns who require a secure, non-slip mounting solution to protect their optical investment and maintain a consistent zero over extended field use.
