Pondering ideas for a rapidly deploying/take down stock for a small 22lr rifle I'd like to setup for my backpack while keeping the weight low. Looking to avoid having to thread/unthread anything, deal with pins, etc. For legality purposes the stock folded needs to cover the trigger assembly (otherwise its a short barreled rifle if it can fire when folded).
I was thinking some 1" aluminum tube with a hinge on the bottom (recess slot for the trigger) would be slick if it can lock up at the joint decently. I was wondering if something like a pair of 15lb pulling strength rare earth magnets might do the trick (the joint should mostly be tension). Obviously can't beat on this assembly but if it would hold decently stable it would likely serve my purposes and make for quick break down. If the flush ends aren't stable enough I can recess the joint into one of the pieces (with a protruding insert from the other piece) to add a bit of stability.
Anyone with magnet experience have any opinion if this would potentially fly before I go ordering some magnets to experiment with?
Anyone have other ideas I'm overlooking?
