I just went through this process for quite a while, your only bet is to get one ordered from manufacturer they’re not making them readily available yet
Yeah I called Brux and they are doing a run in 4 months which might be the best bet. Usually x caliber and mcgowen are quicker but don’t know if I wanna go that route.
McGowen had mine to me in a month and I custom ordered the size. Not only are they great barrels their prices are some of the best. I did a 25 cal, 7 twist, 1.2 shank finishing .950 at 18”.
