ralfus,
I have an A-Bolt in 6.5 Swede, which is a long action. From bolt head to bolt handle, it measures, 5.200" and bolt face measures, .495". If you are going to list it for sale, you should probably Google A-Bolt, A-Bolt II and A-Bolt3 to find out which version your short action bolt is. I hope this helps. RJ
