以前看到过这里有枪友（wildcat?)说过 psa 的bcg is made by Toolcraft (the OEM). So, in terms of mil. spec., they are the same. But, I have read notes like this from the production description of Toolcraft:

"
Please Note: Some dealers utilize a third party coating service to keep their costs down. If purchasing a Toolcraft bolt carrier group from one of these dealers, Toolcraft will void the coating warranty. All Toolcraft Bolt Carrier Groups sold by Arm or Ally include the manufacturers 100% no-questions-asked warranty.
"

PSA (including premium) vs Toolcraf, 是否 Toolcraft的coating 要好些，比如更润滑？希望两个都用过的（或听说过的）同学不吝赐教。
