The mounts are machined from billet 7075 T651 aluminum and all aluminum parts are hardcoat anodized. The Torx 20 ring 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.

NOTE:

The SR-4000 is designed for use on rifles with MIL-STD-1913 or STANAG 4694 rails, and is especially suitable for extended Picatinny rails combined with night vision equipment. The SR-4000 will fit most 34 mm scope tubes except for scopes with extended erector housings, such as the US Optics TPAL/EREK.
