This link wasn't working for me... Either way, it's not hard to navigate Copper Customs website.. Just go to Rifles > Lee Armory > it's the first option.
I've heard absolutely nothing about these Hungarian BFPU's OR Copper Customs... However, I did speak with a Copper Customs employee over the phone by the name of Omar. He told me that their current run of Hungarian BFPU's by Lee Armory are some of the best they've received from Lee.
Time will tell... I went ahead and ordered some Surplus AK74 furniture from Rob Ski's website along with some other stuff. Regarding the BFPU look, I'll probably go in with a scotch bright pad to make it look... more bfpu'esque, but I'll make sure I take some before pictures for y'all to check out...
If I get it by this weekend I'll give you guys a good range report.
