Great backpack for ar pistol - Elite Survival Systems STEALTH Covert Operations Backpack

I purchased this to carry an AR pistol that I built with a 10.3" barrel and a Law Tactical folding buffer tube adapter. This pack easily fits the pistol with a 20 round magazine and room for spare magazines in the main compartment. The Velcro is plenty strong and the supplied loops and straps can be arranged to hold an intact pistol or rifle with the buffer folded. I put my M4 (14.5") upper on the lower and it will fit in the pack but it's a tight fit to close the zipper. The pistol is 20.25" folded and M4 is 24.5". This appears to be a well built pack and has plenty of flexibility for various setups. The frame protects the pistol on the sides but the sides are not padded as the description States.
