I am working on a Winchester Ranger Model 120 (serial # L1927011).

My problem is that the action will not completely close while the barrel is mounted.

I disassembled & cleaned it.

Without the barrel, the bolt will properly close and the action works normally.

With the barrel attached the bolt stops short (approx 1") & the slide jams.

I have disassembled & assembled it numerous times.

Looking for help. Any ideas?

Jack
