So, I have a project in mind: I want to make an AR-15 that works like an AK-47. Why? Because America!! Seriously, though, I mix Coke and Pepsi sometimes, I don't really have a reason sometimes for my projects other than mere curiosity. That being said, a lot of people like features of AK (cheap ammo, more power) and AR (ergonomics, mounting options etc.) There are 2 platforms I want to marry that attempt to mix those two guns, but do them in 2 different ways: KS-47 and PWS. PWS has a long stroke piston system, much like AK. I think piston system is beneficial if you want to shoot cheap 7.62x39 ammo (otherwise what's the point, right?). The downside is that it needs hybrid mags that are not as available, don't feed as reliably, and usually cost a bunch. KS-47 works with AK-mags, but runs on DI. Putting them together is a different issue altogether since it's hard to tell with PWS what part is proprietary and what isn't. They are kinda secretive about that (if anyone has any experience with disassembling them, your help is appreciated). I found a machinist around who agreed to take on the project should we have some modifications needed (pretty sure we will). Why not just buy an AK? For one, it seems like a fun project to me. Two, I have a 300BLK 16" upper I from PWS that I can't sell, so I'll have some parts to play with. Three, I like the idea of breaking up upper and lower for transportation, I like flattop rails, and I like AR buffer system. Anyways, if you guys have some input on how to go about it, your advice is welcome.
