Had a 760 come in for a stock refinish and clean and oil. While disassembled for clean and oil I noticed there is no bolt carrier spring. So I ordered one. Reassembled it with the new spring and it won’t lock-up. Took out the spring and shortened it still won’t lock-up. Disassemble again and try the spring out of my personal 760 and still won’t lock-up. Is it possible some early models did not have the spring? Looks to me like all it does is make unlocking easier?
OK, I kept shortening the spring until it locked up. I only have two coils left. The clearance on the action bar lock is only .008 feeler gauge will fit, .011 won’t fit, Bob says 10-20 thousands. The action bar release button is a little hard to press. In the 760 tape Bob took the bolt apart and the spring in that was like a pen spring on the firing pin. The springs in the ones I have are bigger and slip down around the bottom of the firing pin.(way down where the inner bolt goes down around the firing pin). Still trying to figure this one out.

Took out the spring and reassembled. The clearance on the action bar lock is 33 tho. Bob says he likes about 20, but Remington says 40.
Answer:
It seems to me that there are some that do not have a spring. DO NOT QUOTE ME ON THAT. Let me do some research and get back with you.

Seems kind of odd some would have it and some wouldn’t. Everything else looks the same to me.
Answer:
Well as I remembered some (most) do not have anything there. I know many of the diagrams have a spring pictured but sooooooo many guns especially the older ones just do not have it. The auto’s need it because they close so much faster and the firing pin could hit a soft primer and the gun go off. Bob says that the early 760’s didn’t have the spring and he can’t remember the new ones having one either.

Thanks, My .35 Rem, was manufactured in 1979-80 and it does have the spring.
