In the process of brainstorming ideas on how to attach the magnum side arm to the drop leg thigh attachment for the armor, I came up with this idea.

I used a piece of 0.25 gauge aluminum sheet lying around from a previous project and bent it 5 places to form box type of shape.


For the foam parts, I cut out the center pieces so that the aluminum part can be inserted through both foam pieces.



For the magnum, I screwed in two 8x3/4 size screws closer to the back end of the magnum. The concept is to slide the screws down the slots on the aluminum piece and lock in place just like most household items that attaches to walls.



Here is the view from the back side of the attachment. Bottom pic is in the locked position.



Here is how the magnum looks attached to the leg attachment. The bottom pic is how it looks right side up. It's very secure and it won't come out unless it's pulled out (safe from kids who likes to grab).



Please let me know what you guys think of this idea compared to the rare earth magnet concept.
