I am cleaning out the safe again due to new arrival at house (damn gun shows). This is a first run gun serial # 180-. Blued with a b-square mount on top, not side mount. The gun has a bird cage flash hider on it. I took it off at the range and found out why it's there. The break is threaded on I prosume it was a professional install. The gun will shoot pop cans at 100 most shots. The group became larger with flash hider off. The asking price is $425 with 2 mags (high caps that function) not Ruger mags. Shipping is 20 extra to your ffl. Not a new gun has some honest wear but not beat up. Would prefer calls over emails not around computer all that often. (402)520-2433. Thanks again 66er (Matt)
