So I just built a new AR-15 using a Criterion barrel and an Aero Precision Bolt Carrier Group. It is chambered in .223 Wylde.
I also purchased some go, no-go gauges jsut to be safe as I also did a barrel change on my old AR-15.
I did a quick check of the go and no go gauges and the old bolt carrier group I have passes without any issue on both rifles, but the new Aero Precision bolt carrier group I have fails the go gauge (It will no close) on both rifles.
I did not remove the extractor and ejector for this test, but I typically do a quick test first by guiding the gauge into the chamber before removing it.
Is there any reason why it would fail the go gauge (1.4636 min gauge) on that bolt only?
This is a 5.56 nato min gauge and the chamber is .223 wylde, but from my understanding, it should pass the 5.56 nato gauge without issue, and it does with my other bolt.
