Step 1:
Remove stock safety selector from properly cleared rifle:
Step 2:
Mark a line parallel to the existing lever through the center point of the stock lever.
THIS STEP IS CRITICAL. If the line isn't parallel to the existing lever, the new lever will be crooked and your selector won't be able to rotate from fire to safe properly.
Step 3:
Using a small file, make a groove to accept the male projections on the JP replacement lever. An accurate and well sized groove is important.
Step 4:
- Place the new lever into the groove for alignment and mark the center position of the hole in the groove.
- Drill a hole ~1/4" deep using a #29 drill bit
- Tap the hole using an 8-32 tap
Step 5:
- Secure the lever to the safety using the included machine screw.
OPTIONAL
I'm a nut about stuff being symmetrical. Since the new lever does not match the old lever in appearance, I replaced the original lever as well.
Step 6:
Remove the old lever from the safety using a hack saw.
Important: Keep the cut as close to the lever as possible to leave the remaining safety as long as possible. If you cut too much off, the final product will drag/bind because the lever will be too tight against the receiver.
Step 7:
- Clean and square up the cut with a file or sandpaper.
- Repeat steps 2 thru 5 on this end.
I applied a small amount the blue threadlocker on the screw threads.
Total time from start to finish was about 45 min.
