This M16A4inspired clone opened my eyes to the world of building your own AR15! It doesn't have any Colt of FN/FNH parts, but it does include things like the Trijicon ACOG TA31RCOA4CP, MaTech BUIS, and Knight's Armament M5 nonfree floated rail.

If you're looking to clone this rifle and aren't as concerned with 100% authenticity, this AR15 build is something to consider!
