Anschutz 6922 riser

[Buckeye]

Can anyone help me to determine the size of the mounting screw of the 6922 riser?

Get a set of calipers and measure the outer diameter of the head, the outer diameter of the threads, and the length of the shaft under the head. Get all your measurements in millimeters. the The thread OD in millimeters is the thread size and the thread length is bolt length (e.g. a 3mm OD thread that's 18mm long is an M3x18). The head size is just to make sure that the replacement screws you order will fit into the hole on the side of your riser.

Hope that helps!
