Looking for new Tactical Backpack

Does anyone know where i can get a tactical backpack, that has a place for a AEG on either side of the backpack? I've been looking for one of those types of packs for a long time to accommodate my M-4 and also my M-14 when i have to use my pistol in CQB when ammo is dry for both guns. The pack in particular that I'm looking for holds the guns on the outside, has two clips to hold the gun to the side of the bag, and a place at the bottom of the bag for the stock to sit, and has the barrel of the guns pointing towards the sky. I would be much appreciated if i could get a link to a bag I'm describing, or at least the name of the bag im talking about, thanks.

here are some

for this one, you can put the stock in these side pouches and get a big elastic band to hold the guns barrels up

basicly same Idea if you want it sideways,
but you can strap it horizontily on the back of the backpack
