Easy for those that aren't comfortable with "pinning" - Primary Weapons Systems EBT Mod 2 End Plate and Castle Nut

This was really as easy as it says. I did have to remove it once to take the tube out one revolution. It was a little tough, but it came off. I did have to tighten it a few more clicks than the instructions stated. Has a cool look to it too. The end plate pushed the detent spring in easily with no bending.
