I'm looking to change out my barrel from a 243 to a 308. Is there anyone making a pre timed barrel for these rifles?
A rifle barrel is not "timed" so not even sure what you are talking about. Also, if you are not familiar with go and no go gauges and what they are used for, changing your own barrel is something you should NOT attempt to do. Rifle barrels screw on the action, bottom out and then the chamber is cut, to give proper head space when barrel is tight............Rifles with barrel nuts, like Savages and Ruger RPR, you screw the barrel down until the head space is right and then tighten the barrel nutNo go gauges????
I don't think a AR barrel will work simply because of it not needing a gas port for the action.
I thought about buying a take off barrel, but I have no idea about timing it.
