So I think the mystery had been solved
Does anyone have experience with the NEA/BCL receiver set? How much of a difference is having a receiver built from 6061 t6 aluminum have compared to milspec 7075 t6? Will it matter if one adds a decent BCG and barrel?
Did I panic buy a registered paper weight? LOL
Nah, it doesn't matter. For all the grief that many throw out because of NEA's past transgressions most of it are the results of butt hurt and knee jerk reactions.
I had one of those Z marked receivers a few years ago, and it was fine. I'm sure this BCL batch is fine too.
