Thanks for flaging my radar on this one GG! Yeah, the guy did some hours of head scratching on those details. My hats off to who ever just to have seen it threw to the end. All tho, I can't bring my self to see any practical upgrade to the SKS or AK. There may have been if and thats a big if the shell is light weight aluminum and did a pair of AR push pins for upper/ lower release. He uses the SKS trigger so that pretty much puts it in as a SKS FCG on the inside. Its cute but the MP40 length of the grip to chamber distance is a not so cool back step. Back when I did prototype one offs, you dont put alot of planing into just what the final weight is going to end up as, and then it ends up as a "next time" configuration. Heck, I still have a block of aircraft aluminum I was going to build a AR styled light weight lower for the SKS. Building an 8.5 lb SKS odd ball is easy.... build a under 7 lb one and you really got a home run on your hands in the one of bucket list. Some day, I'll finish the current AR 45 pistol on Grease gun mags I'm farting around with time to time. Oh, for 950 bucks the guy is asking, clearly..... it was a labor of love.
