The bolts on my bolt carrier assembly from WOA looks like they have already been staked. Is it common for bolt carrier assemblies to come "pre staked." Should I assume that the bolts are adequately staked with no need for me to do anything else? Thank you.

Unless you specifically buy a stripped bolt carrier with the key seperate, your gas key bolts should be staked by the mfgr. But some bolt carriers are not staked from the mfgr. I have a CMT carrier that is not staked. If the stakes look like they have a good bite on the bolt heads you don’t have anything to worry about.

Most problems arise from carriers like mine where the bolts were not staked.

either that or the dealer where you got it from staked it before he shipped it

Call me paranoid but I always ck bolt tightness and restake them , as my 1st one came loose after 75rd's and when I ck'ed my second one the bolts were less than tight . For what its worth !
