Description
The Spuhr SP-3602 is a one-piece ISMS (Ideal Scope Mount System) scope mount for Picatinny rails, made for riflescopes with a 30 mm main tube. It sets the scope centreline 38 mm / 1.5 in above the rail and has 6 MIL / 20.6 MOA of forward cant built in, adding usable elevation for long-range work. Spuhr’s current marking for this mount is SP-3602M.
The mount is 126 mm / 4.96 in long and weighs 261 g / 9.2 oz. It uses hardened steel side clamps to grip the rail and the body carries Spuhr’s accessory interfaces for ISMS add-ons. A 10-degree levelling wedge is included. Spuhr notes the mount will not fit the Sako S20 or rifles with two-piece rails, and that rear top covers made from autumn 2023 no longer have alignment grooves.

FAQ
When should I choose the SP-3602 over the SP-3601? Both are 30 mm, 6 MIL ISMS mounts; the SP-3602 is 8 mm taller (38 mm vs 30 mm), which gives clearance for scopes with large objective bells or for rifles with raised rails or night-vision clip-ons.
What rails does it fit? MIL-STD-1913 Picatinny rails. Spuhr states it will not fit the Sako S20 or rifles with two-piece rails.
