I am building an AR and have built over 30 and this is the first time that I have ever not been able to get the barrel nut/gas tube to line up.
I am using Aero Precision's BAR barrel nut with their upper and their handguard. It came with like 5 shims and none of them get the barrel nut close enough to line up. It always falls either too far from the gastube hole or too close so when its torqued it passes it up.
I am stumped as to what to do. It looks like it needs more barrel shims.
