Post a picture of the HRL markings. The only bolts I know of are HRT.

I've never seen a HRL marked M14 bolt. There are some things about the bolt markings that make me wonder.

I never heard of it, and never saw one. The markings look different than the HRT, which was a different sub contractor.

I also see the slight Pr!ck Punch marking, which shows the High Pressure Proof round was tested.

The "HRL" marking is mentioned in the April 1963 Gun World article M14: Boon or Blunder? by Jack Lewis. In that article, Mr. Lewis was referring to defective Harrington & Richardson bolts being pulled out of the U. S. Marine Corps supply system by the end of 1962. The defective Harrington & Richardsion bolts were marked HRT and made by Textile Machine Works. IMO, "HRL" is a typographical error in the April 1963 Gun World article. Other than Stevens' citing the April 1963 magazine article in his book, I'm not aware of the "HRL" marking being mentioned in any literature on the M14.

Every USGI M14 bolt I've ever seen has well spaced markings. The steel supplier identifier on this HRL bolt, A27, is not evenly spaced with the top two lines. Also, the steel supplier codes on Harrington & Richardson bolts used letters, e.g., ACR and CDR. The "A" in A27 is not fully struck, unusual for something that would have been stamped by machine. I may be incorrect but the A27 marking doesn't conform to HRT bolt markings.

It seems odd that an unknown bolt manufacturer shows up forty years after the last M14 bolts were produced.

Thanks from budster

Is there any other way to identify this bolt, say machine marks, or by measurement. It kind of baffles me that someone would take the time to put incorrect markings on a bolt they were trying to pass off as real.

The only thing I can suggest is that You take it to a Machine Shop and have them check the Hardness on the "C" Scale, to make sure that it is not a Marked Up $ 20 Chinese Bolt!
PS If the Hardness reads in the mid or lower 40s You have a Chinese Bolt, a GI bolt should read in the 50s or even low 60s!

There is another possible explanation but I'll refrain from disclosing it here, for valid reasons.

Could it be that someone is trying to make some Easy Christmas Money?
You would be surprised how many Amateur M14 Parts Entrepreneurs are out there and what Length they go to to make a Buck from the Uninformed, most of the time it is with Magazines, Bolts and Oprods!
My suggestion is that one should buy Here in Our PX, that way You know who You are dealing with and have a recourse if You get taken advantage of!
