M17 Grip Retro Fit SOP
1.) Take apart old grip, move pins over to new grip frame in exactly the same spot.
2.) Install New Sear, Sear Spring and Cam Gear.
3.) Test Fit the grip onto the gun, and move the selector switch around.
4.) If the selector feels notchy clicking into safe, turn the cam gear set screw clockwise to thread it into the cam gear, turn only 1/4 turn at a time. As long as the cam gear is not rubbing against the sear, it should work.
Put a tiny drop of oil onto the surface of the sear
5.) Add a second bolt bumper onto bolt.
6.) Air up the gun (use a remote line with an on / off) and test fire it. It should not fire at air up in safe, and the one shot in Semi or FA is normal.
7.) Adjust trigger to set trigger again in the sweet spot.
