I'm tempted to YOLO a Zastava Vuk since Silencershop has free tax stamps for them right now. My biggest concerns are that I'll get an endcap strike (Gayco said the bore diameter isn't as forgiving as the Wolverine and Putnik), and that I'll have to buy new HUB adapters since apparently the threaded portion is too shallow to accommodate mounts with integral muzzle brakes like the JMAC X37.
