ok, next.
2. loose stocks.
inside the stock, the recoil spring tube
(A) is attached to the stock bolt
(B,) thats attached to the receiver
(C).... right in the middle with no way to access it, the A&B parts would loosen.
the bulletin was a modification adding curved washer and straight washer to prevent it from turning, placed in the middle.
problem.
you couldnt just add the washers. (though many did and ruined their guns.) it would increase the length of the system ever so slightly. enough to change the positioning of the locking pin into the adjustment cap. this helped destroy the receiver when the bolt recoiled too far.
so, not only did the washers have to go in, a smith had to drill out some wood the size of the washers thickness combined.
the most serious problem that could occur is having the factory installed stock bolt come loose from the reciever. over zealous owners would over torque a stuck recoil spring tube that could rust to the stock bolt if wet or abused, and in doing so, one could accidently loosen the stock bolt at the receiver. problem is, the recoil rod is inside the tube and all you achieve is to disconnect the stock bolt from the receiver. it wont come off until you get the rod out. it has to pass thru the recoil spring tube!
not good at all. when that happens its 'smith' time.
heres the bulletin.............
