These are the AR carriers I had in our shop at the time. I will add more manufacturers as they 'come through my hands' so to speak. Of the brands listed (so far)I would only consider Colt, LMT & BCM 'proper' staking. Everything else should be restaked with a MOACKS tool by Ned Christiansen. Or at least by using a hammer and punch/chisel moving some metal into the carrier key screws. When the keys shoot loose the AR becomes a single shot or worse as it can try to feed a live round with an empty still in the upper.
