Impact CNC Machine is pleased to offer these Springfield Prodigy Steel Mounts for the following optic footprints:
RMR
SRO
Holosun 507c/508T
Holosun 507 Comp
These are made of carbon steel. They are nitride coated and come with optic mounting screws.
Please note: The thread pitch on the plate is 6/32 (where you mount your optic). The thread pitch on your slide (where you mount the plate) is 6/48. The factory short screws (6/48) will work great with this plate. Please do not try to install the screws labeled for each optic in the holes in the slide. As always clean the threads and apply loctite on all threads however we do not recommend red loctite in either case (plate to slide or optic to plate). Blue 242/243 will work well.
