When mounting fast fire III on a pic rail is it recommend closer to the eye or further toward the barrel
Thanks
Another question I just purchased a pic rail for a Mossberg 20ga and installed, recalled seeing in a post about a 336 rail is that for drilling and tapping guns or just better to use on a already factory drilled and tapped. If Id be better to purchase a 336 rail will the holes match up on a Mossberg 500?
Thanks
