RIP,
USNJoe is correct, but he didn't go far enuff, Essential Arms NEVER made a rifle, they only produced lowers & stripped at that, their designation on the receiver is "J-15", the quality is OK for a good every day plinker, if the rifle is in good shape & good parts it shud sell from about $850 to $1,200.......
BUT !!! if the rifle/carbine has an upper that is post ban it must remain that way...., according to the law that is...........
