I am building an AR 10 using an Aero upper and lower. Since I live in Commiefornia, I will need a mag lock system as I am going featureless. It is my understanding that the Aero lower is slightly wider than other DPMS lowers. For those of you who have assembled an A.R. 10 using and an Aero lower, what mag lock systems have work for you?

Hello all, I live in commiefornia and I’m going featureless on my new AR 10 build. I am using an arrow upper and lower and will need to have some type of mag lock system installed. What is my best option on an AR 10 Aero lower. I think I’m correct in saying that The lower on the arrow is very slightly wider than other DPMS lowers. Therefore, not all systems will fit. What mag lock systems have worked for you? Mag lock with king pin, Juggernaut or others?
