New carry-all bag at Weapon Blender which is large enough to fit your gear in there including compact airsoft guns, plus back-up weapons. Airsoft guns with folding stocks would fit in there too so you can hold around 1 primary weapon and then some back-up plus more tactical gear. Apart from that capability, it's actually cheap too as it costs US$18.99.

• Measures 30in x13in x14in.
• 4 total exterior pockets, each big enough to hold multiple pistols, knee pads, magazines, etc.
• Massive interior compartment with hard floor pad can fit up to 12 guns (32 inch max). Due to the weight, we don't recommend fitting 12 guns in this bag.
• With most loadouts, this will fit your primary weapon, secondary weapon, sidearm, magazines, vest, holsters, knee pads, gloves and several other miscellaneous items with room to spare.
• Some examples of guns this will fit are: all MP5 series (including full stock), M4A1 (fits at an angle), M4 CQB, G36C, M4-F, M933/733, G36K, G36E, G36KE, SIG 552/551, AK beta spetsnaz, any AK with a folding stock, SCAR, all SMGs, basically anything with a folding stock.
