The only non civilian model I am aware of is the green M40 scope, but civi models do have a SN, usually on the underside near the turrets, not on the "retile" bell. As far as BDC dials, I don't know where else they would be...
Have a specific model in mind?

 

It's an acctrac miltary version



Isn't that the model?

the only thing that is on the scope is "3x9 Redfield"

 

New red fields are low end leupolds.

 

Mentioning Redfield reminded me of situation where I acquired Rem. 700 w/ Redfield 3x9 scope on it and it was defective. Since Leupold has taken over that brand name called them about possible repairs and said they were not set up for that. Leupold did offer me a trade in for the scope and take 30% off of any of their Leupold scopes. Don't hold me to the percentage quoted and don't know if they still offer the program but that is how I ended up with my FXIII 6x42 scope, good solid piece of glass.

 

There is an "accu-range" scope and an "accu-trac" scope made by Redfield.
OP, can you post a pic of the scope?

 

Yes a pic would really be helpful. During the Viet Nam war USMC M40 rifles used Redfield 3-9x40 Accu Range scopes that were mostly green anodized but later were matte black. Civi versions were mostly gloss black. Don't believe any AccuTrac scopes were used in the military but just about anything is possible. The AccuRange scopes had a so called Tombstone reticle on the lens that was controlled by the power ring and also had two stadia wires in the upper portion of the lens. How it all worked is a bit much for this thread but first we need to know what you have. Description thus far is vague.

AccuTrac, civilian scope. To the best of my knowledge never used by the military but like I said almost anything is possible. I saw a box end on google that said both AccuRange and Accutrac on it, so I think one can basically call it an upgraded version of the AccuRange.

 

The Bullet Drop Compensator (BDC) came after 'nam. Both the Accu Trac and Accu Range had the tombstone range estimation. They all had serial #s as far as I know.

 

according to the repair facility Iron sight Inc. military versions do and commercial versions don't....

Here's the email response from them....

There are 3x9 Redfield Scopes that have serial numbers and then there are those that do not.

The military obviously had serial numbers.

The scopes Redfield made, were not distinguished as military or commercial. However, there are a few military issued scopes. This would be true of say, the Weaver M73B1. Weaver made these scopes, and the military used these scopes, as well as civilians. There are M73B1's that have serial numbers, and some that don't. That would be true of the m84, etc.,

 

Old thread I know. I have Redfield 3-9X commercial scopes with serial numbers, so don't know how they got that idea.
