A majority of the guns at GP Storage are bugged and you cannot pick them up. Some you can pick up the ammo and others you cannot pick up either. I also had this issue with a few backpacks in that area. It's so frustrating. A couple Commandos,Riot Shotguns, Hell Fires, a backpack are what I know for sure are not allowing you to pick up. Also, the name of the guns do not display and the Triangle loot button notification is not popping up. I recommend avoiding this zone when parachuting. It is an awesome place to go if you have already looted. I won one game of Fives there and it was a fantastic ending.
