Spuhr Unimount ISMS picatinny mount Ø30mm, 0MOA/0MIL

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.  The  rings  are  diagonally  cut  for  increased  visibility of the elevation and windage turrets (US Patent 8,733,011).
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.
Screws come pre-waxed from the factory to ensure proper torque values. The mount is shipped with a manual and a “wedge” leveling key.  

NOTE: Designed for use with MIL-STD -1913 or STANAG 4694 rails, and is especially suitable for bolt actions with 1-piece Picatinny rails.
Will fit most 30 mm scope tubes except for scopes with extended erector housings, such as the US Optics TPAL/EREK.
