Few probably don't already know about the problem with the bolt, but the YT guy clearly shows not only how the front trunnions are improperly riveted but also how the trunnions are improperly machined.
Time-indexed:
Interestingly, the chamfering on the top trunnion holes, which should not be there, _could_ give better-than-spec strength if PSA used swell-neck rivets there along with actually using them for the bottom holes as they are supposed to do.
Machining the trunnion improperly and using the incorrect rivets in general is the kind of 90s-era bush league garbage reminiscent of how Inter Ordnance and other trash outfits did their builds.
It's good info for the suckers who already bought PSA AKs that a MAC 90 bolt can be used to replace the OEM bolt, though.
