John Wick Gas blow back pistol. Used in 5-10 airsoft battles. Comes with BRAND NEW HK-ARMY HPA tank/hose/Primary Airsoft attachment. Also comes with 2 mags, one needs cheap replacement part to stop bbs from coming out. Also comes with laser attachment. Just to be clear I have only used the gun/mags and laser. The HPA setup is brand new and has never been used. Everything is in working condition except for the one mag which needs a replacement part.
