I love my UTG!!!
Its very durable Ive put mine through hell and and it came back on top it has one main rifle area where it can fit 2 20in ARs and it has another compartment where you can put two GLOCK cases in and about 12 30rd AR mags off the pouches.
Heres the breaker though it cost a massive $60!!!!!!!!
UTG Ultimate Combat 42" Gun Case Digital Camo
I JUST ordered a Voodoo Tactical double rifle case (with room for a couple pistols). The reason I got it over most the other ones was for the backpack straps. I know 5.11 tactical has one with and one without, but the Voodoo was only $99 shipped from Amazon.

If yours is for shorter rifles you may be able to get away with the 36". The only reason I went with the 42" is because I have a couple rifles that are about 44" long, but my AR would have fit in the shorter case.
