AR Forge markings

[Okiegunner]

I suppose it does not really matter (just kind of cool for those who have an interest in this stuff)

My AR upper and lower both have forge markings. Both are different.

The upper forge mark is located just above the front end of the forward assist. It is a square (Brass Aluminum Forge)

The lower forge mark is located just to the rear of the trigger, at about 11 o'clock. It is the keyhole mark of Cerro Forge.

Both the upper and lower forge markings are located on the starboard side of the rifle.

Just thought I would share with you guys.
