Replacing O rings on the Alfa Proj pistol
Posted: Fri Feb 08, 2019 8:40 pm
Any recommendations on how to slide the barrel back into its housing without nipping the edges off the two O rings (listed as #58) as the barrel passes over the openings for the two retaining grub screws?
On taking out the grub screws I found there were little slivers of rubber underneath each of them. I didn't realise what they were until I had replaced the old rings with the new ones and tried to slide the barrel back in with gun oil to help its journey.
I noticed another two slivers of rubber in the grub screw holes and on removing the barrel, I found two neat nibbles out of the new rings. The base of the screw holes must razor sharp, and on looking at the old rings they also has flats of both of them, so it must be a problem that predates my ownership if the gun.
Any tricks up your sleeves would be gratefully accepted. The packets of replacement rings are expensive. I am lucky I ordered two sets but am loathe to use the #58 O rings from the second set until I have an assured way of getting them past the grub screw holes without being shaved flat!
