Swapping Bolts????
M60 was issued with one bolt and two barrels.
Barrels were marked and each time we drew the guns, we used to other barrel; barrel A this time, barrel B next time and back to A after that.
You get the picture.
Reason was so that both barrels had similar wear; both barrel (extension) and bolt wear together.
Alternating wear kept all 3 parts relatively similiar.
If one was used all the time and took all the wear, when the other WAS used, it would be very much different from the bolt.
Could be bad.
Swapping either bolt or barrels with another gun was a huge NO-GO!!!
That could be very bad.
So..., if a person is of the mind set to have a backup bolt/carrier, seems it might be an idea to switch out fairly frequently so that both bolts/carriers wear is similar and both stay close to the wear in the barrel extension; keeping the headspacing on each bolt close to the other.
Thoughts?
Oh, and granted, on a civilian semi-auto it likely is nowhere near the issue it is on a 60.
Ah, the 60.
It was a love/hate relationship.
I do miss it.
