I had heavy barrel douglas put on by champions choice and warbird did the unitized gasblock for me. I painted it from reciever forward with aluma-hyde2 and it turned out great. I bought a super match stock that was glass bedded and put it on it it. I put in a rooster33 op rod guide.I have not shot it yet but i think it will be a tack driver. Still waiting on cheek rest from rooster 33 and sadlak piston.
