Mike at NodakSpud has announced that they’re retro A1 lowers are ready.
These guys make the BEST US AK receivers, and the FAL receivers they made were great as well, so I have every confidence in these things.
I’m going to get one to build up my NIW Colt A1 upper.

Thats what I’ve been waiting for! 
OH SWEET MAMA!!!
After looking at their site, and not seeing one, I am highly disappointed they didn’t go with or at least offer a slab side.
They said that’s coming…
We will be making other versions also.
They will be;
NDS-601 (slick-side/no rib or mag fence)
NDS-XM16E1 (w/rib, no mag fence)
NDS-16A2 (current style A2 design)
