I use the TBR brass catcher, not a cheap unit but I believe it is the best available. It folds out the way so you can clear a jam or check to make sure the chamber is clear. It does not cause ejecting issues even when it is heavy with empty cases.
sometimes, my brass will bounce off the stall window, and ill catch with my own hands!![]()
Check the 3bucc ones. I use them on ARs with scope, RDS or just flap top and they work really well. You can buy 1 bag/frame and then multiple mounting blocks 1 for each gun.
