If you are looking for an innovative piece ideal for CQB but aren't looking to spend a lot of money, consider the tan G&G Combat Machine GR4 100Y Folding DST M-4 Carbine Blowback AEG Airsoft Gun from Airsoft GI. The G&G GR4 100Y plastic Blowback AEG airsoft gun is a very interesting addition to G&G's already impressive lineup of M-4 AEGs. It features a polymer body and rail system, keeping it both lightweight and durable, and a folding stock that drastically reduces the overall size of the gun, making it perfect for close quarters engagements.

What really sets the 100Y apart from G&G's other budget-friendly AEGs is its 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 the front of the gun, allowing the user to tuck the battery inside 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.

Highly customizable as well as comfortable, this gun gives you a lot to work with for not a lot of money. Its light weight, folding stock and short length will provide you the advantages of speed and maneuverability when you need them the most. Adaptation is the key to survival, and this adaptable gun will help you survive any encounter. Overall, the G&G GR4 100Y plastic blowback AEG airsoft gun is a budget-friendly airsoft gun that is sure to impress even the most experienced player.

Product Information:
Another great G&G! I got this gun last august and it is performing great! First, exterior. the body is actual polymer, I did a side by side with my bro's crosman R72. The receivers, hand-guard, outer barrel, grip, and part of the stock are made of said plastic. the iron sights, top rail, stock, charging handle, and trigger are metal, to be expected. the stock folds to the LEFT (very nice for right handed shooters) you have to squeeze the two arms together, then fold it. It stays in place by friction, you just have to pull it back straight. I've found the straight stock to be a bit long, and I usually run it folded. The rail is very unique. Its much like an S-system m4; a long rail that attaches to the upper reciever extends out and clamps onto the RIS. A little switch in front of the front sight holds it in place. When released, it just slides off toward the front. The space inside is tight, barely fits a 1400 mah nunchuck. I'm getting a peq-2 box to mount and wire to the outside for a larger battery. Now the internals are a typical combat machine, ver 2, blowback, spring release, and a spring that shoots (in mine) around 330 fps. No problems so far, great G&G weapon!
