Aimpoint Micro standard

1) There is one Torx socket at the end of clamp adjusting bolt on the side of the mount. (See Fig4-2). Before installation, loosen the bolt to release clamp using included Torx wrench.

2) Open the cam clamp handle. Slide the sight into rail and close the clamp handle, while still loose.

3) Tighten the clamp adjusting bolt using the Torx wrench. This will tighten the clamp to the rail to moderate degree. Try to open and close the clamp handle, adjusting the clamp bolt so it is neither too tight nor too loose. This will avoid the mount becoming loose under recoil.
