Hey guys. During my adventures in gun world, I've acquired equipment and have maxed out this smallish bag that I have for my tools and parts. I need a back pack sized bag or larger, but not too large.. that has a hard floor and lots of compartments with a large open main area. I would like to put my spare gun parts in there like my springs, buffers, bolts, kits, tools, cleaning kits, and other misc items (ie. my grease ). Any ideas?
