He’s full of vodka and BS like most russians. Kalishnakov was never a weapon designer. He was a plumber that completely ripped off the design of the German Sturmgewehr 44.
I like my AR’s simple and light. But that's just me. Some I see, quad rails with lights, lasers, foregrips, bipods. Then you have these scopes with holo sights mounted on an offset mount. BAD levers, extended take down pins, mag well grips, huge stocks...All on one rifle!
To each his own, I guess...
I love seeing references to the STG-47
