Product Description
The rings are diagonally cut for increased visibility of the elevation and windage turrets (US Patent 8,733,011). The mounts are machined from billet 7075 T651 aluminum and all aluminum parts are hardcoat anodized. The Torx 20 ring and clamping screws are zinc-nickel coated for corrosion resistance. The screws come pre-waxed from the factory to ensure proper torque values.
The SP-4001 is designed for use on rifles with MIL-STD-1913 or STANAG 4694 rails, and is especially suitable for bolt action rifles with 1-piece Picatinny rails. The SP-4001 will fit most 34 mm scope tubes except for scopes with extended erector housings, such as the US Optics TPAL/EREK and the Nightforce BEAST.
