While in Arizona, I took time to look around at some new manufacturers. Grant Timberlake, proprietor of G&R Tactical, had posted information about an interesting AR builder in Phoenix. What is so interesting about another AR?
According to Grant, the ADS (Advanced Defense Systems) LLC rifles have the barrel finished in black oxide by Robar, the Arizona coatings specialist. He noted that Robbie Barrkman’s black oxide is “on the expensive side” but that the completed gun has a beautiful and even finish.
