Complete upper assembly from a brand new, unfired PORTED Glock 19C. This was from a Gen 3 model and was only taken out of the box for pictures. Same as a normal Glock 19 slide only has ports cut in the slide and barrel that expel gas out of the top of the pistol which pushes the muzzle back down to get you on target faster. Reduces recoil, increases speed of follow up shots, and it especially looks cool because it shoots flames out of the ports when fired. This is a full OEM Glock factory kit but is compatible with any aftermarket frame kit as well (brownells, polymer 80, shadow systems and others).Mates up with gen 3 frames but will also function with a gen 4 if you have the right recoil spring or adapter.
