I am the second owner of this SMC9, I put in the downgrade yellow nozzle and a new bucking. I will include the original ones. Previous owner drilled a small opening on the original mag to feed easier, time to time the follower will snag on it but I never used it. I also have a HPA drum mag adapter for the angel customs modular drum mag Price for the SMC9 is $275 and with the HPA adapter $340 I accept PayPal or cash with pickup I wish ship
