Christensen arms CA9. Comes with pistol brace, 10.5 inch carbon fiber barrel, 3 prong flash hider, trigger tech drop in trigger and an angled foregrip. Takes Glock mags. Does not come with the holosun sight, supressor, or vertical grip in last picture. I’ve put about 300 rounds through it. Shoots fantastic. Smooth recoil and firing. Fun fun to shoot and small enough to keep for a home defense gun. Make me offers. Open to trades.
