HRA Markings Charts-4.7M & 5.6M

[Rolling Thunder]

All charts represent a very small overview of very specific serial ranges.
They are not the only markings possible, there could be others.

All are presented at face value and it should not be construed that all representations are original as manufactured.

Thanks for posting this data. It backs up all of my data that the DRC knob was standard equipment on HRA rifles.

Mozzer,

The first chart IS in the 4.75 range.

Hmm, the first one listed looks like 4.76 to me, i must not be able to see the first one. no differences then?

I have 4.754.xxx

mine does have some differences from the first 4.76. though i do feel better that my correct has no hole in the ferrule. i thought that was a mess up

mozzer,

About two weeks production from yours to the first listed. Makes no difference.

Thanks Dave for the information. It is appreciated!

Hello - excuse the dumb question, but what is significant about these serial number ranges? I have 4,762,7XX and it has an HRA 5-54 barrel, D65 HRA U bolt, HRA op-rod and trigger group, HRA elevation and DRC windage knobs, and a SA stock. I ordered two SGs a few years ago and received this HRA and a SA 5.7M.

Where would an HRA U.W. bolt fit into the list, if at all?
