the barrel is a winchester,GI, std contour. and when the rod is in place its perfectly lined up with the gas cyl/piston. movement of the rod is fine untill it contacts the base of the barrel.
i really dont want to take any off the bottom of the barrel so as to keep it in its original configuration. i'm worried if i do, the SA rod may not work properly, like jump the rail or something.
after some filing/polishing the rod fits and doesnt bind, however the amount of metal left at the top where it rides under the barrel is very thin. worries me that the guide may split it?
one more cup of joe and i'm off to the local gun show to see if any are out there.
we'll keep you posted
