i have just received FSN-01F(with a short military barrel) from marstar, not as short as Fsn-01k, but still... and i am not happy with it. It really looks like it is a surplus rifle, it looks like Petr Novohorodky (or what ever his name is) rummaged through used/spare parts bin and cobbled the rifle together. The folding stock is grey, receiver is reddish, the dust cover is grey, the barrel grey again, the mags are familiar bluish paint, and the front hand guard is well well used. All internal parts look very well made and brand new though. The cleaning kit is definitely well well used and cleaning rod is made of 2 parts one is new and one is old. there was some rust inside the front hand guard too. I can live with all that though, but the most serious thing is that the barrel seemed to be well used too. I started cleaning it, and the black stuff which is burnt powder (not cosmolite grease) kept coming out on and on, i gave up after 10 patches, and this is supposed to be corrosive ammo The riflings where the bullet engages riflings seem to be worned out somewhat It really looks like i got a surplus rifle assembled from spare parts. So i worried about how much life left in this barrel. I really expected to have military, but unfired barrel! after all these rifles soled as new rifles. was i wrong expecting that? I would like to return it, but I am afraid they will give me hard time, but on the other hand it says nowhere on their website that I should expects a used barrel. So shouldn’t dealer somehow indicate that a customer should expect a used barrel? My first CZ rifle was excellent, everything was brand new. You guys probably have more experience with CZ, what do you think?
