Poly-tech is top notch guano. The Poly-tech legend is the best Ak, period. You've got a good AK man.
Although Polytech are good AK's they are not the end all be all.
IMHO the Polytech were much better guns than they were given credit for back in the hayday of Chicom imports. Wish I had bought a few. Polish and Yugo AKs are a cut above as well. Romanian's not so much.
