Don't know if this will help, but I personally know of 3 shooters who independently bought Bushy ARs, from different retailers. In 2 cases, the barrels were bent, in the third there were serious machining defects in the action. All 3 required shipping back to Bushy for warranty work, and on release after repair, owner had to do the Brady all over again.
This was about 3 years ago, and in my mind, a brand-new gun out of the box, should not need to go back to the manufacturer.
Having said that, the AR platform is here to stay, if nothing else, because of the plethora of accessories available for it. If you limit yourself to a (relatively) exclusive firearm type that does not have much aftermarket mods available, be prepared to end up with an essentially stock firearm.
*PS* for $800 you could get a decent DPMS M4 flatop!
