Does anybody have any experience with Essential Arms?  Are they as good as Bushmaster or Colt?

Any help is appreciated.

My lower is an Essential Arms.

From my research/understanding the lowers are average/above average.  They did not manufacture a complete rifle, so you need a 'paper trail' to prove the lower existed as a rifle prior to the 1994 ban.  Since Essential quit manufacturing lowers prior to the ban you can 'assume' it was a rifle before 1994, but there is a difference between 'assuming' and 'proving.'

My CAR-15 type, was assembled by Bushmaster when they were just Quality Parts.  I've had good luck with it, no problems, and as good as any other lower.
I've heard that Ruger actually did the casting for EA.
