If it's an Armalite it's probably a "B" because there aren't many "A"s out there yet. But see this Armalite tech note:

Tech Note 101

It is an armalite "B" but is there anywhere I can determine if it's ar10t or ar10a2 or ar10a4c
All it has on the side above the serial # is rifle 7.62 mm and under that AR-10
Thanks for your help I'm still learning

Ahh! The mysterious Armalite code thing. From Armalite's FAQs:

"Five models of the AR-10B series exist:
--AR-10B is the base model of the new ArmaLite line. It is loosely patterned after early 1960 era rifles, and is produced largely for nostalgic reasons. The charging handle looks like an upside down trigger and is located at the front of the carrying handle. It bears early M16 furniture in a brown epoxy finish and a rear sight elevation window at the rear of the carry handle.
--AR-10A2 is the Infantry model, virtually identical to the latest M16A2 Service Rifle, but scaled up for the 308/7.62 cartridge.
--AR-10(T) is the target model featuring a 20 or 24 inch long medium weight target barrel.
--AR-10A4 is a flexible combination of the AR-10A2 and the AR-10(T). It is generally identical to the AR-10A2 except that the upper receiver and gas block are manufactured with the “Picatinny rail” sight mounting surfaces of the AR-10(T). Removable metallic or telescopic sights are optional.
-- SuperSASS is the most versatile AR-10 rifle inasmuch as its variable gas system is adaptable to a sound suppressor. "

A2 has a fixed carry handle like the original AR-15.
A4 is a flat top.
B is black furniture. If B is not present it's green (or something else?).
C is a carbine (16" barrel and collapsible stock).
F is forward assist.
N means national match trigger.
NM means national match barrel and trigger.
If the caliber is not .308 it appears in the model number, like 10TBNF338.

So an AR-10A4BF is a flat top 20" rifle with a fixed buttstock, black furniture and forward assist. An AR-10A4F is the same thing with green furniture.

There's a better explanation of the models around somewhere, but I can't find it.

The lower receiver is identified as an "A" or "B" by the first letter of the SN, but AFAIK that is the only model designation on the rifle. You will see things like your EA1151 all over the rifle, but these are part or supplier numbers (EA1151 is a picatinny rail gas block for AR-10 or M15). My impression is that the modular nature of the beast lends itself to any number of variations in configuration, so a few configurations are made as stock, but not so marked. In fact, you can get Armalite to build anything you want no matter how weird or useless, but a model designation for such a beast would be as long as my truck's VIN.

This is what's in Tech Note 101, but I did not verify it with my rifles, and it is not correct as of this moment. My new 10BNMF serial number starts with "US".

I think we need a FAQ.

I just checked, and my other two Armalite 10s SN starts with US too.

Unk, could you give us a hand here?
