Jet DesertFox finds the G&G Armament Piranha TR GBB Pistol to be problematic in this "Straight Outta the Box" episode. An in-house design by G&G Armament, its is the third Piranha pistol and this comes with a rail on the slide for mounting optics as well as an under rail for lasers or weaponlights. It comes with the patented outer barrel hop-up adjustment tool, whirl cylinder value to reduce frost built up, and a 6.03mm tight bore barrel.
