I am getting a new 5.56 upper from BCM, 14.5" midlength lightweight, MOE handguards, 1.5 Battlecomp brake, on a AP lower, SSA-E Geiselle trigger, CTR stock and CS buffer spring with T2 tungsten buffer.
I haven't ordered a bolt/bolt carrier group yet and wondered if you all could give me an objective idea as to the difference between say the AR15Performance ITS Extreme Duty Bolt Carrier Group, 5.56-9310 alloy superbolt, and Nitro coating of them (or getting the superbolt and the Nickel Boron Coated M16 carrier)
vs the BCM Ion Bonded M16 bolt carrier group

Trying to go as light as possible here with the LW build. I want extreme reliability here.
Thanks for your assistance!
