Check out what just came...my Phitz mandolin case.
For $18, shipped, I'm pretty happy. Its padded all the way around and seems more than sturdy enough to hold a Scorpion and 5 mags. I wouldn't check it in an airliner, but from house-car-range-etc. transport I think it'll work great.
Shown is my braced Scorpion (25.5" OAL) with a CZ 30-rounder and my SBR'd AR-15 (26.75" OAL, collapsed). The Scorpion fits like it was made for it, the SBR is a tight fit. With the optic hanging out like that on the SBR, I think it'd be extra careful how I toss it around.
I was going to get some Kaizen foam to pad the inside, but it holds it so well I don't think I'd need to. This is a pretty sweet little case and very discreet. SBRs/braced pistols are fun!!!
