BLUF-Is there a measurement from the bottom flat of the bolt carrier to the top of the entry point on the gas key?
Backstory-I have one carrier that wants to lightly strike the gas tube on a new build. It gets worse if I apply pressure to the bottom of the bolt carrier. It wants to do the same on several other builds as well, though my Sionics and LMT carriers are fine in the new build. I've identified two things so far:
1-Gas key appears to be .0075 higher than a Sionics BCG I compared it to.
2-The internal hole in the gas key barely allows a gas tube to fit inside, although it's not a friction fit.
BCG already went back and returned once under warranty, but currently do not plan to throw the manufacturer under the bus. I picked the BCG up on the forum here while grabbing some other items I needed and was hoping it would function until I could grab a few Sionics BCGs. The manufacturer claims to hold gov contacts for BCGs, so I at least expected the bolt carrier to be good. I'll probably be out about $50, and I can live with that if needed.
