Ive been looking at AR15s for a few years now, but have been hesitant to spend that kind of money on something i didnt know alot about. Ive considered buying a new, factory rifle, used factory rifles and used custom builds, but I could never find exactly what I wanted.

The gun is going to be a carbine length piston drive, 556 upper with iron
