I made one from a 1/4" HSS drill, In the middle I cut a small v for the grubscrew to hold it, After i'd finished and blued the ends I found a spare one in the bottom of the gunslip!

I had to make a grubscrew by cutting the head off a setcrew then using a junior hacksaw to make a slot to drive it home, Turned a little too hard and snapped the slot so i'm not sure it would come out again!

The genuine one has a threaded hole which makes them inherently weak!, Bad design



The gun shoots with low power, The bronze ring looks worn out to me so I bought a new one, Never replaced it and have no idea where the heck it is now!
