    Firing flatastic

    I was trying to hold off until my ARC frame arrived, but couldn’t help myself and tossed it on a different frame. This thing runs super smooth and RIP recoil.


    I also tossed on the 320 Reactor High sights and it’s a beauty.


    Guess I’ll have to try the Glock slides now ¯\_(ツ)_/¯
