The G&G GR4 100Y Blow Back is an extreme short CQB Automatic Electric model. What makes it extra interesting is the presence of a Blowback function. It offers a handguard covered in Picatinny rails that offers maximum ability to customize.
This premium G&G AEG features a rugged polymer receiver, stock and handguard, making it one of the most durable, lightweight but aggressive G&G AEGs on the market! It features a premium ball bearing 8mm gearbox, Li-PO ready wiring, and a high torque motor!
The receiver features a long Picatinny top rail on top for mounting optics. The rear LMT type sight is removable. The front sight is also removable.
The LE stock is simple, effective and offers a low profile result.
It comes with three sling attachment points. There is one at the end of the stock, a steel sling swivel at the end of ther eceiver and a QD one at the rear part of the rail system.
The handguard is an innovative design and comes with Picatinny rails at 12, 3, 6 and 9 o'clock. It allows you to mount accessories like a tactical vertical foregrip for stable shooting or a tactical light.
What really sets the 100Y apart from G&G's other AEGs is it's innovative outer barrel/RIS/battery storage design. Just in front of the removable front sight is a small latch on the RIS unit. Once this latch has been opened, the entire outer barrel/RIS assembly can be slid off of the front of the gun, allowing the user to tuck the battery inside of the RIS unit. This means no more worrying about a bulky PEQ box or having to rewire the gun to the rear for easy battery placement.
The motor, gears, bushings, and wiring have been upgraded to make this AEG 100% Li-PO ready out of the box! G&G has upgraded their standard gearbox design to include a high torque motor, as well as 8mm ball bearing bushings providing an incredibly high rate of fire as well as FPS with a Li-PO battery!
The adjustable hop-up unit is located behind the dust cover. This can be reached via the functioning charging handle that can be pulled backwards and released.
With the pneumatic blow back feature, which cycles the mock bolt with every shot, you get an intense sense of realism combined with the high performance nature of this gun's gearbox, which is superb in terms of delivering both power and reliability.
G&G utilizes a proprietary pneumatic blow back system, which means elimination of excess resistance/drag on the motor (and hence the high rate of fire even with the blow back function).
The model comes standard with a precision inner barrel of a 6.04 mm diameter and a 240 mm length. The metal High Capacity magazine that comes with it holds 450 BBs.
