I use the NEA upper and a bushnell trs-25 cuz I can still use irons with that set up. Holds zero even after disassembly. And u can check it against yours irons just by lining them all up with your eye. Very lightweight too.
Sorry can't speak on any of the other brands. Only used the NEA. But I've read good things about the BC tactical handguards. Very nice build quality I've read.
