Casefull: truly excellent.
Imagine if all AKs had the side mounts for a rail and "AR-styled" red dot etc sighting system.
AR and AK owners would then have a somewhat valid comparison between the totally different types of rifles, especially the AK-74 using the 5.45 rounds.
silvermane_1: If you've watched Rob Ski on AKOU, you might have seen the very premature internal wear on the US-made Century RAS, and one of the IO AKs he tested. IO even shutdown their AK production line for a while due to so many problems.
Nobody besides AKOU seems to shoot 2,500-5,000 rds. in such guns while periodically checking bolt lugs, trunnions etc, showing us the visible results. Headspace is checked.
The PSA is one of the US brands I would trust.
