Re: M1A Scout Problems
To the OP,
How many rounds have you put through the rifle? When is the last time you removed the op rod and greased the bolt roller and roller recess in the Op rod?
The only time I have seen the rollers "pop off" was when the stud on the bolt was:
1 - worn out due to lack of grease which ruined the roller, bolt and op rod or
2 - the Factory SA "cast" bolts wore down prematurely. SAI used some pretty questionable bolts for a while and they wore quickly due to "soft" material but they have since started using better products.
A GI bolt would fix that issue if kept greased.
The dent on the breach face is more than likely caused by the extractor smacking it when the bolt closes, typically a cast SAI extractor that does not have the right relief angles cut, again, a USGI extractor will more than likely keep that from happeneing.
SAI will make repairs but its doubtful they will install USGI parts. They will put a new bolt and probably an Op rod in your rifle and send it back. If it were me, I would have it fixed and when you get it back, put a USGI bolt, roller and extractor in your rifle by a competent gunsmith and keep the SAI parts for spares.
This is why M1A's with genuine USGI parts are much more valuable to someone who has worked on them or shot them much. Smith Enterprises and LRB are the only "aftermarket" companies that make parts on Par with USGI ( actually often better ) than the original. But as anything in this world, good and cheap do not often co-exist so expect to pay considerably more than a Springfield Inc. Part.
"The firing line" forum is a good place to look for some GI parts
Hope this helps.
