Spuhr SP-4001 ISMS Picatinny Scope Mount - 34mm Rings, 0 MIL / 0 MOA, 30mm Height, Screw Mount

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 Gen3 version features a fifth clamping screw, allowing the SP-4001 to be mounted in a cantilever fashion. 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.

The IDEAL SCOPE MOUNT SYSTEM series  of mounts feature seven set of interfaces to  attach any of more than 40 different  accessories and has a bubble level integrated in the rear plane of the mount  body to prevent canting of the rifle. The rings are diagonally cut for increased visibility of the elevation and windage turrets (US Patent 8,733,011).

The mounts are machined from 7055 T76511 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 mount is shipped with a manual and a “wedge” leveling key.
