Flattening of Blackout brass at the case mouth is normally the result of the shorter case (rather than the longer .223 case) being able to spin in a smaller radius and hitting the upper receiver case deflector...perfectly normal.
When I bought them new they were packaged separately with each package labeled. Each gauge was also labeled. The Go gauge had go on it, and the sealed package had go on it.wow, what did they send you? no packaging on the first saying what it was??
Yeah I know right. I went through a lot of hassle shipping my barrel back, and then the gauges. The letter said this was a rare occurrence, but the barrel manufacturer told me this happened the other day to another one of their customers.TA DA! View attachment 75913
Gotta shake my head wondering how many other BAD Sets were shipped? Plus builders setting barrels on uppers with them.
Anyone making barrels would likely very quickly figure out something was wrong. Most builders are basically part assemblers and it could cause some problem as was the case here. Someone doing this on any scale could do a quick field check of the suspect gauge by putting it into chambers known to be in spec.TA DA! View attachment 75913

They sent me a label to ship to them, so shipping was covered with them both ways. I did have to pay to ship my barrel to the barrel manufacturer.Well, I know I don’t want to buy chamber gauges from Forster. They should have offered to reimburse you for the shipping charges you incurred , in my opinion.
