“After having this bolt carrier(458) for over a month and shooting over 200 rounds it is flawless. I was expecting a few jams along the way during the first 100 rounds while breaking it in but not one jam. This is one of my best builds that has been flawless. I know only 200 rounds but 458 aint cheap even reloading your own. My experience with Arm or Ally as a customer is A+A+”
“Nice, bcg. Seems to be reliable, don't know if I can afford enough .450 to really stress it. Fires and cycles as it should, looks nice and well made.”
