These are nice packs. I have thr stealth covert ops that holds my 18" AR10 while broken down. The muzzle presses up against the fabric a bit though. A minor improvement would be to add a flexible pouch that allows a slightly longer barrel to protrude while still being able to zip up the main compartment.

I also have a stealth sbr backpack that I like even more, it fits my 7.5" 300 blackout pistol nicely - using a folding stock and quick detach suppressor.

It would be nice if it came with additional velcro straps or if you sold additional velcro components for organizing.

Overall am happy with them and would recommend
