>>663253I built this one, it has a 8.5 inch barrel. I just got the optic on it, do I've only shot out to 200 yards, but I seen videos of people getting to 700 yards. But adding a vertical fore grip changes it from a pistol to a AOW which requires some fancy paper work, tax stamp, and a few months of waiting.
As for your photo, I never shot a scar 17, but I always liked them. I've shot ACRs a lot which are similar and they feel good.
The main thing is weight for me. I can build a ar pistol and have it in a 300 blackout and do everything from person protection to harvesting deer since it's basically a 308 bullet inside a cut down 223 casing.
Used a ak for my woods gun for several years, but the weight just got to me and my lame bad back.
