Grendel Barrels in stock at Brownells

Just for clarification: A go or no-go gauge, while useful, will NOT tell you if you have a throat issue as they only check the chamber. go/no-go gauges worked in my stoner barrel but it's throat is noticeably short.

That is true. I wish there was a throat gauge, like a machined bullet to check both the chamber and throat.
