I believe most M14 parts were parkerized using manganese phosphate. SAI uses a similar process for most parts, but I believe the more recent rifles have a blued finish on some small parts that are made overseas, such as the elevation knob, sight base, gas lock, etc.
Rifles under the 250k serial range seem to have a uniform parkerizing very similar to the original M14.
Early SAI rifles with USGI parts, will often have parts with a greenish tint that was caused by the parkerizing reacting to cosmoline.

Sounds good thanks for the info.
Reason I ask is it seems that a usgi FH that I saw recently was darker in color than my grayer, 350,000 serial number m1a standard. I would like to drop this thing into a usgi stock, usgi FH, and refinish it to match a GI M14. Maybe even add a faux selector.
So would the usgi guns actually be darker thab my grayish m1a or is the FH reference just anecdotal?

^^^ Correct. The military specification does not require a specific color match and from the carbines and M16s I worked on in the Air Force there was always some variance in color between the parts. About the only time you will find an exact match in color is when a weapon was arsenal reworked and the whole thing was reparked.

Real M14
Here is a pic of a full auto M14 in my possession. Manufactured 1962-64. It belongs to my department and is assigned to me.

Looking at the pics the bolts are marked "kk" & "ww"
The windage knobs are "wce" & "bme"
And the trigger is "cm-n"
All markings are new to me. Different from the traditional usgi markings.. I was under the impression that no new m14's were being produced other than Smith enterprise..
Can someone explain these conflicting marks..and as the poster said "real m14's" I assume they are of the same grade or better than usgi..why I never heard of these particular marked parts on this forum? And why are these not sought after for home builds or replacement parts as the usgi ones?

Here are pictures I took of real M14s that are ARSENAL REBUILT in the armory where I work:
Fixed the opening statement for you, added arsenal rebuilt.
Nice rifles by the way
Both bolts were made by Winchester, as indicated by the 66118 manufacturer number.
WCE was a subcontractor - Wilco Electric Co
BME was a subcontractor - Bruce Machine and Engineering
As noted above OM indicated Olin-Mathieson Chemical Corp, which is the parent company to Winchester.

I didn't realize we were discussing the pictures I posted months ago. RNGR3
75nova, if you've never seen those, check out my thread here: http://m14forum.com/reference/180945-winchester-olin-mathieson-parts.html
A few photos down you'll see manufacturers such as Han-dee Spring, Stanley-Humason, Hesse-Machine, etc. all making parts for Winchester. Thought you might find it interesting. RNGR1

I just replaced the trigger group in my Springfield standard with a Milspec group and the rifle has a darker finish than the trigger group housing.
