Anyone know what the barrel thread size is on a brno 601? I want to put a fast twist 6x45 barrel on one I have laying around here. - dan

Should get you headed in the right direction
I'm pretty sure it is a 26mm x2mm pitch. One can fit almost any barrel to almost any action, assuming he wants to badly enough!
