Update...got a problem
When I tried to test fire it with the identical looking 550 tube in it, it jammed often.
after cleaning it seems to only jam on the last round in the tube. the bolt flips the last round over Lead pointed downward and hangs up on it.
When I hand operate it, the shells feed into the chamber and eject without a problem. Even the last one.
Any suggestions as to what is wrong?
Date code is "DO", which i take to mean 9/1977. But the barrel also has 76 stamped on it, so maybe it's a 76 barrel in a rifle assembled in 1977.
Also I found some more of the rifle. The spring and a broken metal plunger weren't missing, they were jammed way up in the inner magazine tube.
