Thread: The ever reliable Stirling Model 20.. why won't they work?

Same virtually as the Norinco JW14 and JW14a if I recall. It would sound to me that you have an issue with your trigger group - that is a different world of hurt pulling that particular trigger assembly apart. The manufacturing quality of the internals in that assembly can be a little variable, and it sounds like you might have a dragging burr or something on the internals that are making it difficult for things to reset when they should.
