I recently picked up an AX short action with the large firing pin. While I haven't tried it with a small primer load, in the event the large firing pin doesn't work properly, what are my options? Buy a new bolt assembly? If I buy a new bolt, do I need to be concerned with headspace or is it like my Desert Tech, where the bolts are essentially interchangeable? Does having the firing pin bushed correct the issue?

Ai at small vs large firing pins
Made an impulse buy on an ai at and don't know much about them... I know mine has a folder and the switch barrel system. I've been reading about large vs the new small firing pins. When did they start making with the small firing pins? How will I be able to tell which one I have? Is there...

@lowlight ’s theory is the issue with large pin vs small primer is headspace. With theory being if you let a smith take the exact measurements for your individual AI action, you likely won’t have the problem.
If you do, your options:
Buy new bolt and/or firing pin assembly
Having it bushed.
Both work fine and won’t have any issues.

A relatively frequent complaint with M700 and Accuracy International actions (and others) are cratered primers with factory made ammunition. The root cause of this is from excessive clearance between the striker and the hole through the bolt face. When fired, the primer cup flows into the void...

i have had 6 new bolt assemblies in the shop in the past week. All the bolts measured within .0005” of each other. In other words they were identical. When I measured the large pin assemblies they were perfect. And just yesterday I measured 2 bushed bolts, mine and a friends they were within .001” of the new large & small bolts.
have it done by LongRifles or a quality known smith that can work on these bolts. They’re as hard as a honeymoon pecker. I’ve seen a few that they touched the face to much and set it back .005”. That would put all factory barrels out of spec.
Buy AI small pin or Long Rifles would be safest bet.
Protrusion is adjustable also - as an option, results may vary of course. Not typically a recommended path to take.
