Can anyone can help me figure out if the M1A bolt I picked up at the crossroads show today is USGI? Your help is greatly appreciated. This is my first post here, and the bolt is for my M1A Scout.

The numbers are:

7790186

SA Z1B

I may be wrong but I believe that if you look close, you'll see that the 6 is actually a 5 as in 7790185.... That's what's on my all USGI SA. Bolt would be USGI Springfield Armory.
Thanks for the help Hawk. Unfortunately it is a 6 as in 7790186.

I payed $70...is that a fair price?

Thanks again for your imput.

IIRC

7790185 Early bolt without roller-put on when put in use.
7790186 Complete bolt

Here's the tricky bit- I believe if the number is followed by the SA on the same line, it is a Springfield Inc. bolt. I.E.

7790186-SA with the next lines number being the heat treat #
F00079

This is the printing on a TRW Bolt:

7790186
TRW ZH

Snayper-I believe yours are SA Inc., if not I hope someone will correct me, I will search further, someone (probably Bill Ricca) had a post on this a while back, I just have to find it. HTH

No question, that is commercial reproduction Springfield Armory, Inc. but the F means forged. If you have one of these with a "B" at the start of the second line it was machined from bar stock. Walt Kuleck verified this with Customer Service at Springfield Armory, Inc. earlier this year.

Regarding my suspect Springfield Armory USGI bolt:

7790186-SA
YO2

The seller represented to me that this was a "Springfield Armory USGI bolt and not a Springfield Inc. bolt". I should have known that the "-SA" next to the part number means Springfield Inc., but the fact that it has a hardness test dimple on the top surface like my TRWs and Winchester threw me off. It was also reparked and looked "new". I don't think Springfield Inc. dimpled their bolts.

Anyone disagree?

You have excellent taste in firearms. I also have a special love for my Kimber. You can never go wrong with them.
