So I wound up with a PSL kit... due to the lengthy queue in front of it, it will probably be next year before I can do anything with it.
Smurfing around looking at PSL stuff, I found the pictures below. It's an airsoft "PSL" and he didn't leave room for a magazine, but it might be possible to jigger around that.
I'm not a fan of bullpups in general, but this... I dunno. I could get used to something like this. Figure a 26" barrel and a nice scope...
My mad woodworking skilz are barely above "caveman", though.
