i think maybe they have fallen off badly in quality control as our 2 have very well staked gas keys, and even the castlenut is staked........ to be honest, i dont know if our castlenuts are staked properly because the nut itself is not actually staked, but the metal adjacent to it is staked into a notch in the nut. not one of the notches where the wrench would go, but a single notch on the opposite side where the wrench goes.
also noticed on ours that they have the shrouded firing pin (which i have noticed are different from every other bm i have ever seen.
something that should be added , ours were made for law enforcement, during the awb, and we bought them less than one week after the banned expired, making these particular ones legal for sale to the private sector.
i have made it a point to inspect every other bm i have ever seen, and have not seen any that compare.
my son picked them out and is my good luck charm i suppose.
i dont have any pics of the cn stake job, but here is the bcg key staking on one of them. they look identical.
we take these to the country and shoot stuff, take them to the range and shoot paper, and just fool around with them. we have a combined 15k rds through 2, and never a single hiccup of any kind. not mag related, reload related, zilch, nada, nothing. absolutely perfect.
it might be a sin, but out of the safe, i would trust them with my life or my families probably beyond anything else ive ever had. (15k reloads with never a stop has had that effect on me)
theys accurate too. legit sub moa
again, i have never seen another bm with shrouded firing pin, good gk staking, or any cn staking other than our 2.
im not saying they are the greatest rifles that can be had, but oh how i do love my "bushamsters"
lucky i guess.
