Designed for use with my Airsoft Rifle. Fits any picatinny rail. The riser has enough space to fit a red dot as well as a sight protector. For screws, an M5x35 and nut works well. For imperial, I can confirm a 10-24 of length 1.3 in or greater will work, it may be easiest to get a long screw and trim it to length.
