@cottox As Biggoron said look more closely at the pictures.. You can carry 2 guns but I'm carrying 3.
@PvtRyan It's not that hard to utilize. In this situation... I had an M4 then picked up an SKS... then I got a mosin. I could use the Mosin til it runs out of ammo then drop it all... the SKS shows up so I pick that up. When I'm done with SKS I drop it for M4. The third gun is 100% usable and maintainable.
