[skeeter149]

I know its been brought up before and I did contact a few that were open but I'm looking for a gunsmith to dimple my barrel and also check headspace to my bolt. Going with a KaK value line with spikes block on the dumpling side. Any advice is appreciated and thank you all for help. If anyone has the go no go gauges and wants to help out I would appreciate it. Let me know and thank you
