RMZ Sear Set Screw
5-40 x 5/8” Allen screw to limit the sear height in the RMZ fire control group.
We changed recently from a 6-32 thread. The 5-40 pitch gives a little more of a fine adjustment. We have also added a 5-40 nut with this to act as a lock nut to insure the position of the set screw remains fixed. This is critical to the smooth and safe operation of the FCG.
