I really like mine, ordered from RustyTX's website last Tuesday night, arrived Monday morning.
42" tan for my 20" AR with A2 stock in tan, and a 33" green for my 14.5"+phantom M4 with an M93 stock. The 33" is a very close fit (without having to angle the rifle in the case, and just barely not touching the foam lip to protect the gun from the zipper) for the carbine with its 31.5" overall length, so if you have a 16" barrel plus a flash hider, I'd strongly recommend going to the next size up. I really liked how I could reposition the hold-down straps closer together so the case would secure the rifle by the handguards rather than the barrel.
There's also a
picture on his website of a Krinkov in a 26" case, considering how the cases are 1-1.5" smaller on the inside than the listed dimension, a 25.5" AK or SU-16 would be a tight fit.
