G&G GR4 100Y CQB Electric Blowback M4 AEG Rifle w/ Folding Stock - TAN

The NEW G&G Full Metal Gearbox Pneumatic Blow Back GR4 100Y AEG is a modular and compact CQB airsoft carbine, perfect for fast paced room clearing and cornering in confined spaces such as indoor CQB airsoft fields. The GR4 100Y features an comfortable folding stock, a seamless top optics rail, and a modular nylon fiber rail system! The GR4 100Y also utilizes G&G’s revolutionary patented pneumatic blow back Version 2 full metal gearbox, which cycles the mock bolt with every shot fired. This unique feature adds an amazing sense of realism, and minimizes wear to the gearbox. The NEW GR4 is a high-quality, high-performance CQB rifle, that costs much less than most comparable CQB Blow Back AEGs. Though this AEG looks as though it is only designed for close quarters combat, it can easily reach out and hit targets up to 150 feet away. This G&G GR4 is an amazing bargain, due to its precision internals, pneumatic blow back Version 2 gearbox, and aggressive design!


One of the most unique features of the NEW G&G GR4 100Y AEG is its side folding stock, which allows you to quickly and easily deploy the stock for long range engagements or fold it to the side for close quarters combat. This feature is perfect for indoor airsoft scenarios and during fast paced games when you need to quickly move with your weapon. The GR4 100Y also features an extremely rugged Nylon Fiber reinforced polymer upper and lower receiver, which decreases the AEG's weight and maintains structural integrity. The GR4’s rail system is also constructed from nylon fiber, and features over 18 inches of rail spce! Additional optics and accessories can be easily added to the 12 inch seamless metal top rail, which also feature removable front and rear iron sights. If you’re tired of traditional M4 AEGs and want something with unique aesthetics, a lightweight design, and rugged construction the NEW G&G GR4 100Y AEG is perfect for you!


G&G has reinforced the build of the gearbox to be on par with their more-expensive "Top Tech" line of $350+ AEGs, making this Blow Back GR16 CQW Rush an amazing value! In addition, the internals have been enhanced right from the factory to deliver an extremely high rate of fire [ROF] right out of the box!

G&G’s pneumatic blowback gearbox uses air compression to drive the mock bolt back and forth, reducing stress on the gearbox and improving shot consistency. Add in a precision crafted inner barrel, and you have an amazingly SOLID fully automatic Blow back CQB AEG at an unbeatable price!
