Breacher - Shell Catcher (Bộ Hứng Vỏ Shell 1 Điểm Gắn)

I wanted something to catch my shells from the Breacher, and found this Pivoting Shell Catcher The only problem with it is that it has two points of contact on the rail, where as I need one in order to fit both of my 5 shell holders by Sillybutts. It also needed to be relatively low on hardware, ruling out magnets (which are kind of a pain any way). The only hardware you need to make this work is one m3x25 bolt, one m3x30 bolt, and two m3 nuts. Also you need the mesh bags or any other contraption to hold the shells. The 30mm bolt secures it to the Pic rail, and the 25mm acts as the hinge. Please comment if you need help or have concerns. Also please tell me if I should make the opening bigger.
