Visually inspect your firearm’s receiver for burrs around the screw holes and remove if necessary. Remove all oil and grease from the holes in the receiver, the base screws and contact surfaces. Place the scope mount base(s) on the receiver. Check for proper fit and alignment. Using a T-15 wrench (supplied with WARNE rings) loosely install the supplied Torx 15 screws. If base(s) fit properly, firmly tighten screws.* For firearms with an Aluminum receiver, Do not use TW1 Torque Wrench, Do not exceed 15in/lb torque. Steel receiver firearms, torque to 25in/lb max.

*WARNE recommends the use of a REMOVABLE thread locking compound for best results.
