The AKDAS Lightweight Collapsing Stock appears to be a 1 for 1 copy of the SIG MPX Buttstock. If it is a direct copy as it appears, then the Length of Pull (designed for a Subgun/PCC), will be quite short. That's not the main problem though. The bigger issue is that the Buttstock rail runs right where the Left side Charging System lies resulting in a no-go for that collapsing style of Buttstock.The Lightweight buttstock is what I was referring to, yes. AKDAS are apparently already making a proprietary version that includes a 1913 interface so this would be plug and play. It would avoid a redesign of the folding stock altogether, and offer some flare for the MCX-at-home crowd.
I suspect JR probably thought of it but if he's reading this, it would be interesting to have his input -- even having this stock available as a separate option would be great.
