Fabrika Broni Lucsnik in Radom or Circle 11, has not exported to US in many years. I beleive they had a rifle approved by a BATF last year.
In the meantime 2 Polish companies export to US. Pioneer, housed in a former adult toy factory in city of Radom. They go out of their way to impersonate FB Luscnik. Their rifles are on par with IO.
WBP is another private Polish company. Their rifles are better quality than stamped Bulgarian Arsenal. I have a coiple of WBPs as well as Arsenals.
WBP supplies Citcle 11 with some parts, and in turn, Circle 11 sells them CHFCL barrels and Beril RSB and rear trunnions.
So you would take a WBP Fox over an Arsenal?
