Remington model 700 dating

It is cstated by seller to not be an sps, but I have found some ADL's were made after Remington started heavy beadblasting like the SPS POS actions that are rough as a cob inside and out.

Thanks Allen Hemiallen: Remingtons are more easily/readily "dated" by the two letter barrel code on the left side of the Remington factory barrel.

That is honor, and there are way too many people in this country who no longer understand it.

Here is some information that you can get from you serial number after 1921Remington's manufactured after 1921 have a code located on the left side of the barrel near the frame that identifies the year and month of manufacture.

More curious if the second generation ADL post, or during J lock had the same rough finish, or just the flat finish that resembles parkerizing more than blueing.

I emailed the owner, but I have received firearms not exactly as the owner implied..a 2# tuned remington trigger that measured 3.7# on both my scales...
