Sub2000 carbine, cambered in .40 S&W, uses Glock .40 magazines. I would guess I have put around 500 rounds through it. It is in perfect condition.
Asking $250. or I am willing to take trades for an AR upper with cash up or down depending on how complete the upper is. I can do FTF in NJ or ship to your FFL if out of state. I have pics, IM me with your email if you would like to see them.
