I have a .204 that I have shot the barrel out of and am rebarrelling to a 6 BR. I have been running a .223 AICS mag and after taking it apart it looks like I should be able to get a BR conversion kit just like I would have to for a .308 AICS mag. I realize MDT makes 6BR magazines but if I can utilize the mag I already have I would prefer to just get the conversion kit. Has anyone tried this?
