Here's some pics off the 'door' I mentioned that some Mannlicher type actions have when sporterized.
This acts as a clip saver on the sporters.

This one on an '88 sporter. They are all the same idea but sometimes pivot from a different point to take advantage of a placement that affords the best/easiest way to fabricate for that particular action.

This '88 pivots the door at the extreme back end of the mag box and uses an extra thin flat spring that is added to the magazine. That spring extends back into the trigger guard and is attached to the inside bottom of the bow and out of the way.


Close fitting door with 'ears' that fit into cutouts in the bottom edges of the magazine.


Door pulled partially open, It's actually sitting on the high point of the rear edge before going over center on the spring.


Door all the way open and spring tension 'over center ' keeps it open in this position for you.


The back edge of the door bearing on the thin flat spring that powers the door open and shut.


That's the other end of the spring. It enters into the trigger guard inside the bow and is secured there. Rounded and polished.
