Yes a long action bolt head is diferent it has a longer collar. 223 long action bolt heads are hard to find, and are nearly non existant. If you attemp to use a short action bolt head on a long action what you end up doing is create a VERY dangourus situation.
Nope the front baffel has nothing to do with the bolt heads, and they are universel between long anction and short action, and everything else.
Your only option is to buy a change over kit from Sharp Shooters supply, that safly alows use a short action bolt head.
