My personal feeling on sheet metal receivers is, not no, but hell no on any of them. I have never read about one blowing up in someones face,but, I don't want 35-40,000 psi under my face being constrained by sheet metal. Just my opinion and my choice.

The sheet metal, or stamped receiver, doesn't bother me so much. But NOT on a Type 56 SKS!  It's the way this whole stamped receiver SKS "experiment" was thought out and implemented.

If they're going to use a stamped receiver in the construction of a Type 56, make it simple, user friendly, and have a simple manufacturing process. Use, (in my opinion), forged steel trunnions and a receiver shell, like the AKM Stamped receivers. All that use of an odd, partial length, CAST trunnion and then wrap it in that weird setup. And, Cast? Really? Of all things that I'd want strong, it'd be the front trunnion!  I really don't know how to describe that process used on the stamped receiver SKS. It's just weird. A mess!

A milled receiver is simple, (not putting down the skill that machinists have and use in operating the milling machines), You have a block of steel, you carve out a receiver with milling machinery, (nowadays, with computer assistance).

As far as Kalashnikov's go, I'd take either when it comes to receivers. I've got both milled and stamped receivers. The stamped guns are a little lighter, but I've never had one fail yet.

Lastly, as far as the Type 56 SKS goes, since there's not really a stamped receiver Type 56 model that was done correctly, there's simply no choice to have to make. (IMO)  And, I don't really want a Cast Receiver Type 56 for use as a shooter, at all. I'd buy one if it was a great price, just to have that particular SKS box checked for collecting purposes. But I'd have to get it at a great price.

it's... not actually  a bad idea in terms of machining. The sks receiver isn't super hard but it's not really that easy a machineable bit. there's a lot of inside cuts i would design around that a two piece receiver would eliminate the toolpath complexity of.

I guess what I don't get is why they went through the extra trouble of making a full wrap sheet metal instead of just a U channel if they were going to make the trunnion sections that large and involved.
