G&G has always been at the forefront of airsoft innovation and design. Constantly providing players with reliable and durable airsoft guns at affordable prices. G&G is one the driving forces that has been, and will be, pushing the limits on airsoft - releasing high quality, unique replicas that will match any player's price point.

The G&G GR4 100Y is the latest addition to the company's line of intermediate level of airsoft guns. Made with the same reinforced polymer as their Combat Machine series, the G&G GR4 100Y is very lightweight, yet built extremely tough. The 100Y features a unique quick release rail system. This gives players the ability to mount tactical accessories while, at the same time, allowing players to easily access their battery - as this gun is front wired. The iron sights on the 100Y can be adjusted for windage and elevation, but can also be removed to make use of the continuous top rail for any aftermarket scopes and optics.

Internally, the G&G GR4 100Y uses the same 8mm version 2 gearbox that have been used in their Combat Machine line and features an pneumatic blowback system seen on other GR4 and Top Tech airsoft guns. This full metal gearbox is extremely well designed and solidly build providing excellent out of the box performance. And just like all of their airsoft guns, the G&G GR4 100Y uses a 6.04mm aluminum tight bore barrel, giving the gun longer range and improved accuracy than most standard airsoft guns. Clocking in between 330-350 FPS, this gun provides players a very versatile platform that can be used in both outdoor and CQB fields and gives them the ability to customize the gun to suit almost any situation.
