its not the only barrel Im willing to use, I have looked at different brands and discussed those with him but as a first custom rifle for me Im letting my smith pick as I have no experience with different barrels just that I wanted a higher end brand even if it meant waiting longer. I saw that I could order barrels myself but aside from being overwhelmed with all the options it seems the 25 caliber is much less common and not regularly stocked as a blank.Is Krieger the only barrel you are willing to use? Other excellent barrels are out there, but there is no guarantee on the wait time. I ordered a custom barrel from CarbonSix and their current wait time is 4.5-5.5 months. Also, IIWY, I would order the barrel myself. Barrel manufacturers have different lead times, call them directly or find a distributor that carries multiple barrels that might have your requirements.
