That is an Essential Arms lower, not Eagle. Eagle is a division of Armalite and they are located in Illinois.

From greybear's link:


Essential Arms
All are Pre-Ban as they went out of business in 1993. (DPMS bought them prior to the Ban) Call DPMS Lower receiver serial numbers begin with EA. Some or all lowers are cast. Light gray coloring. It is rumored that Ruger investment casted the lowers for Essential Arms.


Just an FYI; Essential Arms in Krotz Springs, Louisiana is back in business. I placed an order with them on Friday.
