Details: Used. Spuhr ISMS (Ideal Scope Mount Systems) 34mm picatinny scope Mount. Model SP-4602. 20.6 MOA (6 MRAD) cant. 1.5” Height. Includes leveling wedge. Does not include original box or manual.
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 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 mount is shipped with a “wedge” leveling key.
The SP-4602 is designed for use with 56 mm objectives on rifles with MIL-STD-1913 or STANAG 4694 rails, and is especially suitable for extended Picatinny rails combined with night vision equipment. The SP-4602 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.
RKB Armory’s Opinion: This mount is as solid as a rock. It has some great features, such as built in bubble level, and a slot for a leveling wedge.
