Need Best Price Aero M4E1 Lower

[Frontier Gear]

I picked up my black Aero M4E1 lower yesterday as well as a black Aero Gen 2 lower. To tell the truth, I haven't even taken them out of the box yet. The M4E1 will be for my 12" group buy pistol build and the Gen 2 is for my "budget" build. My son may be the guinea pig for the budget build. I'll post pics later today.
