Thread: Changing AR to A cat from E.

It usually straight forward, my mate is currently doing the exact same thing. All you should have to do is attach an A cat approved stock, take the lower in to prove this also completing the appropriate paperwork and they will remove the E cat status from the rifle. Sounds like your AO is putting it in the too hard basket.

I suspect the reason they may be hesitant is because of potential further proposed law changes.
