Included with this purchase is the rail, dovetail nut plate, 2 steel screws, 2 steel nuts, and an allen wrench for installation. No instruction come with this kit.
1. Remove the OEM rear sight. (loosen set screw, if necessary before pushing the sight out of the dovetail slot).
2. Use the provided allen wrench to loosen the two screws in the pic rail. It is not necessary to remove them completely, but it can be done that way as well.
3. Ensure that the nuts remain in the dovetail nut plate and slide the nut plate into the dovetail notch in the airgun.
4. Center the rail on the airgun and retighten the screws, being careful to not overtighten. Just snug enough to keep it from moving side to side (2-3 in-lbs).
