I can personally attest to these parts. Original rare front site base. Selector and muzzle brake are top notch from very knowledgable and skilled machinist in Poland. A lot of research went into these parts with access to the prototype rifles. As you can see in the article how important wz 80 was to developement of Tantal. Wz80 has selector detents in different positions than Tantal; and all this was incorperated into parts so that they are as authentic as possible. Get this set and you might have 1 of 2 wz80 in the US. Bcax is 100% and we are lucky to have him with us here! I just can't say enough about him. If you want a rare bird this is one to have, especially if your into Polish equipment.
