Re: .308 boltface rebarrel to 223 what are my options?
The feed rails are different on the 22/250,243,308 etc receivers. They do not extend as far forward as a 223 receiver. Perhaps it will feed and maybe not. The smaller diameter 223 case might jump out from under the feed rail prematurely and with the 223AI having some feeding issues in some receivers anyway you may be building a headache. Better off to have the correct receiver from the gitgo and modify rails if needed for the fatter AI round if needed. Just my .02 cents worth. I tore my 223AI apart because I got tired of feeding issues using it for a coyote rifle.
