They all come from the same factory, G&P's are "hand picked."
I have one of those particular ones, it's as good as any ACOG is going to get. Let's face it, ACOG eye relief is abysmal anyways. The "Ebaybanned" or whatever ACM name you want to give it, works just fine.
Personally I have no issue with ACOG eye relief, but this is after using a G36 scope eye relief.....the ACOG feels like a Eotech eye relief.
