Geonox Airsoft gets to test and review the G&G Piranha TR Dual Tone Gas Blowback Pistol that has been in the market for sometime now... "In this video we take a look at the G&G Piranha. It is a GBB. That stands for gas blowback. It runs on gas. And the slide, which moves backwards with every shot, gives it a nice kick, the blowback. The piranha has a split slide. That means the sled is cut in half. The front part is immobile. Only the rear part is movable. This has the advantage that the Airsoft is more gas-efficient because it only has to cycle half a sled. The piranha has a rail on the immovable part of the sled. You can mount a red dot sight on it. Another highlight is that you can adjust the hop-up from the outside. You don't need to remove the sled like with other GBBs. If you want to see more airsoft content, then take a look at Instagram Geonox_Official. Many thanks to Sniper Airsoft Supply, who made the Airsoft available to me."
