Strong steel construction for the gun rack wall mount , sturdy enough and is workable for most firearms or swords, like AR15,AK47,M16,G36, MP5,AWP,M5,SVD and other shotgun and handgun,etc. The gun wall rack is black powder coating and soft EVA foam pads inside to protect your firearms or swords from scratching,slipping and moisture. The size of the gun storage rack is 1/2" wide x 3-1/2" tall and the inner hook opening is 1-7/8",they don't take a lot of space and they are easily placed where ever and however you want. Nice way to display your rifles or shotguns.
