Re: Action Screws
1/4-28 x 1" SHCS on the front.
1/4-28 x 1 3/8" SHCS on the rear.
Screws may need to be trimmed to length depending on the installation.
If you use the badger pillars and the inletting is all relatively correct, minimal to no trimming will be required.
Badger ships their M5 with a 1" and 1.5" and the 1.5" always requires shortening.
