G&P has been a company for a fairly long time now.
They produce everything from parts and accessories to full airsoft guns. The quality of their products has been noted to very good if not great the majority of the time.
The majority of G&Ps line up is mostly armalite style AEGs of all shapes and sizes, although they do have a few M14 and even M249 style guns in their line up. I believe they even make shotgun and some gas based grenade launchers. As it stands G&P has been a long time tested brand for many airsofters and regardless of whether you purchase an AEG or a part, be assured that you are investing your money into quality.
