I have a new firing pin. no baffle though. i have new: firing pin assembly, bolt head, ejector, ejector retaining pin, ejector spring, extractor, extractor detent ball, and extractor spring. I dont see a difference in baffles for sale at midway as far as caliber specific. However i do remember the baffle on my fathers 223 has a long side on it that my wsm and my G/F's 7mm-08 do not have.
