Never saw a need for any of those, except for the BCM. A lot of hype if anything. All of my rifles run very well, and for thousands of rounds. However, I also use good BCG's. The stamping on the side of the receiver doesn't mean too much, it's what's inside that counts. Buy what makes you happy.

i find it funny that psa doesn't use toolcraft bcg's on their new sabre line.
