According to a pdf downloaded from RPA International, the clearance between the cocking pin and the bottom of the cocking ramp, should be 0.004". In my case, there is no clearance and there is the risk of damage.
I have unscrewed the cocking pin carrier about half a turn, to increase the clearance but there is no change. Therefore I am wondering if I am wrong.
Am I going about this the right way?

Best to take measurements between the two collars and email me.

Thank yor that link, Jim. It does not appear on the RPA site AFAIK and is new to me. I will be able to study it tomorrow.

Jim,
Sorry to do this, the day being what it is.
Did you mean for me to send an email to your business, or a PM through this website?
All in your own good time Jim.
