Before purchasing, please check the wheelbase as per instructions:

Phase 1:

- Check the Brand and Model of the weapon

- Check the caliber

- Measure the length of the barrel (from the muzzle to the beginning of the chamber)

- Remove the front sight and the rear sight

Phase 2:

- Using the information collected, consult the “Ribs” table (page 17). If there are multiple models of rib for the same weapon, it will be necessary to check the distance between the centers of the holes (Holes spacing).

- We will use the image above (Fig.1) as a reference to take the measurements of our wheelbase (there are 4 holes marked with the letters “A,B,C,D”). In this case the correct center distance starts from hole B to hole C, but it could be different depending on the Brand and Model of the rifle.

How to check the distance between holes:

- Take a millimeter ruler (rigid ruler, the “meter” is not good) and place it on the first hole of the front sight (A), and check on the table if one of the measurements matches one of the two holes of the rear sight (C or D ). If none of the measurements are correct, move the ruler to the second hole in the front sight (B) and check on the table whether one of the measurements matches one of the two holes in the rear sight (C or D).

- Once the correct rib model has been identified, you can proceed with the order by communicating the code.
