As above really. I want to be able to walk into a gun shop and ask for a moderator 'to fit this please' and be fairly confident they'll have at least one. I'm asking because I'm looking at getting a barrel threaded.
Don't know if it's 'standard' as such, but all my rifles have 1/2" UNF threads. I believe it's the standard factory thread on CZ rifles, but my two A-Bolts have been threaded after they left the factory. I think Browning use 14x1 as standard, for what that's worth?
