Gun racks / storage options

[Spottswoode]

Hey all, I’ve been looking for some options for gun storage inside the cab. I’ve got a bullpup rifle and a 12 gauge and a pistol. The seat-back Molle panels look pretty neat but I’ve also seen an overhead system. Overhead might be problem as in 6’2” and I hear that system can get in the way. Anybody using rear window? Would prefer not to do drilling and cutting and hacking of the truck. Also does anybody know what those straps are just behind the rear headrests are? Just a tie down solution of some kind?

Can you all post your solutions?
