I'm actually really thinking about the x39 JAKL with ACR stock. Zastava M19 at home. And no, the x39 JAKL is still in development More on reddit.com

Sorry for the youtube link, but the reddit app keeps crashing when I try to upload the video. Ok, I discovered you can modify Magpul AK74 mags to fit and function in the PSA KS47... but post Russian ammo import ban, too little too late, right? Well, I butchered up the magazines to work with 5.56. New follower, new spring, and some material super glued to it. It works!! I also discovered that Zastava ZPAP-85 steel magazines can be slightly modified to work in the gun as well, and it fits like a tailored glove. They are perfect, but a little pricey. I tried the ZPAP-85 polymer mags, but they won't lock in without essentially grinding a huge chunk of the back of the magazine off to clear the gun's mag catch tab. Therefore, opt for the steel mag and skip the polymer mag. Before you start asking, "WHY??", there is no functional or advantageous purpose for this gun. I just want a modular rock and lock mag gun, and this fits the bill. It's super fun and definitely raised a few eyebrows at the range. More on reddit.com
