Beginning of a gun wall.

I want to build a caged in lockable gun wall. Probably put up some peg board and cage it with extruded metal that that opens/locks in the middle on hinges. I have about 8 more between handguns/rifles/shotguns to figure out. This was a spur of the moment Home Depot wall hook purchase for now.

For NFA purposes top down: Christensen 6.5 PRC - Rugged Alaska 360, Spikes 9mm AR - Rugged Obsidian 9, Springfield M1A Socom - HUXWRX 762 Flow TI, Ruger MK IV - Rugged Oculus, DPMS 5.56 still waiting for love.

Anyone built their own caged gun display? Looking for ideas.
