    Why a carbine-length gas system? Why not midlength? As far as I know, midlength is reliable while shooting a bit smoother.

      Why FDE in stead of Black? There is nothing wrong with carbine gas. It’s a just a different flavor. Carbine gas will serve you well, especially when the gas port is spec’ed well.

    I like the FDE. And I like the price point.
