Parker lifter mechanism

Your 10ga, 1882 liter is working as intended. The 12ga. gun is not working properly. The trip is either missing or dirty, or the trip spring is missing or broken.

Thanks Chuck. What does the trip look like and where is it located?

The trip is a little tab located at the very bottom of the receiver well. When you close the barrels, the barrel lug pushes it down to release the bolt and top lever. It''s easy lost when the gun is taken apart. If you don't see extending out about 1/8" or so, it''s missing. It can be gunked up and sticking down, or the spring inside the trip is missing.
