your project, well done by the way, strikes me as an AK that is really starting to look like an AR, what with the rail, VG6 brake, picatinny all over, Aimpoint, faux buffer tube to mount M4-compatible butt stock. I guess this is the product of technology transfer, cross-pollination, and the benefit of the Reagan-Gorbachev love fest, huh?
at the same time, we also have the technology transfer going the other way, now with piston AR's chambered in 7.62x39, some even take AK mags, others the AR-type CPD/ASC's, along with half-assed AR side-folders: they fold, but not semi-auto shootable when folded, just going for The Look and Tacticool style points. All thanks to cheap steel-case 7.62x39 arriving on our shores as the motivator.
just a trend observation, nothing more, nothing less.
Like I said, nice looking project. Does it still eject brass (or steel) right-and-forward 30 feet into the next time-zone? which, of course, is in the AK DNA.
