Check the EE. A few dealers there have them, IIRC.

If the rifle headspaces ok with your old bolt, you do not need a new one.

If you are replacing your barrel because it is shot out, then the bolt is due also. I would not run a bolt past 10,000 rounds (even though they can go much further).

Like the others said, EE is the best bet, they pop up quite a bit.

I have seen this statement made on several occasions. I'm not being critical, but am curious as to the basis of this recommendation. Does .gov do this when they rebarrel? If the barrel is capable of going past 10k would anyone feel it necessary to scrap the bolt at that point in order to keep going with the barrel? When rebarreling a bolt action rifle, almost never is the bolt replaced.

Other folks have suggested that 20k to as much as 50k is a more reasonable lifespan for a bolt.

when the bolt wears they wear together probably the bolt more than the bbl. extension.



the bolt wearing would cause a change in headspace and therefore should be atleast checked when "swapping over"

The Government does not always swap out the bolt when rebuilding an M16 type rifle. For instance the M16A2 upgrade kit comes less a bolt. There was a thread here about a month ago detailing old bolts failing in upgraded M16A2 rifles.

The 10,000 round limit is just my advise, nothing more. My thoughts are that the Ar-15 bolt is a weak sister and that the design team went to far with shrinking Stoner's rifle down to .223.

Thanks. I ask b/c there seems to be a wide divergence of opinion on this issue. Bolts are relatively inexpensive, I suppose. But I hate wasting $. A friend has close on 50k on one bolt that he nonchalantly swaps among different uppers. He laughs at me for worrying about dedicating one bolt to each upper.

I'm a little more paranoid and have dedicated bolts for each upper. I have reached 10k with one bolt/upper combo. But things are still rosy, and all I'm doing is blasting in FA. FWIW, I have never broken so much as an extractor, and I shoot alot of Wolf.

Anyway, thanks for responding.
