Installation Procedure


  • Mounting slots in the riflescope base allow you to install the mount into one of several positions. Choosing the position of the mount helps to ensure correct eye relief, depending on the type of hunting shotgun.
  • Weaver USQD mounts can be attached using either two, three or four screws depending on the riflescope model and the selected mount position.
  • Use 2 screws M6x20 to fix the mount on Talion riflescopes; use 1 screw M6x25 for the mount center bore (C).

  • To install the mount on Digisight/Digisight Ultra, Apex, Trail riflescopes, disconnect the adapters (6) using an S2.5 Allen key.


1. Attach the mount to the riflescope base using the S4 Allen key and screws (1) (clamping force – 4 Nm/35.4 in-lbs).

2. Mount the riflescope on the weapon rail and make sure the chosen position is comfortable.

3. Remove the riflescope from the weapon rail.

4. Unscrew the screws one by one, apply a drop of Loctite and screw back until it stops (clamping force – 4 Nm/35.4 in-lbs). Allow the Loctite to dry for some time.
