I built a Russian AKS on a FL receiver couple years ago...
these receivers are top notch, but expensive to build..as this one is a threaded barrel
receiver..
The action is glass smooth ,, just as good as a Poly Legend..
The newest ones have the LOGO moved to the under side where its not as noticeable
My AKs came out just as i wanted .. 50 year old looking.. and it shoots just as good now as it did when it was new !!
