In the natural world, apex predators ( also known as alpha, super, or top predators ) are predators with few to no predators of their own, residing at the top of their food chain. Apex Airsoft Guns embody this spirit when it comes to providing you with the best possible out-of-the-box airsoft electric gun. Apex has taken decades of airsoft designing, manufacturing, and playing experience to bring to the airsoft player a brand of airsoft guns unmatched by anything else on the market in terms of features and price. No fancy gimmicks, no unproven technologies, no window dressing. These airsoft guns are built with function in mind, using proven, off-the-shelf technologies to maximize durability and quality, while minimizing the price.

The Apex Fast Attack series is an great option for players that want durable parts and great performance comparable to competitors like with the G&G Combat Machine M4 series. The solid metal body is rigid and built to withstand tough handling. There is a quick change spring system that allows easier access to swap the spring to the FPS you desire. This is amazing for those that need to reach the requirement to play at CQB fields or simply want to have control of the muzzle velocity. The 6.03mm inner barrel is efficient and assists in keeping the shots on the target. A flat trigger design is installed into this model which allows the airsoft gun to have an improved trigger pull shot after shot. The tri-prong flash hider has an aggressive design different from a standard birdcage design. Additionally, the flash hider has threads that can be utilized to attach a QD mock suppressor. Altogether, the Apex Fast Attack RIS M4 comes with many attributes that make this a force to be reckoned with.

Picked one of these up to drop a redline HPA unit into. I had to do just a bit of dremeling to make everything line up right, but it dropped in perfect otherwise. Gun was super easy to take a part, and honestly the internals were pretty squared away if I was gonna keep it an AEG. body feels great too, very sturdy and I love the classic M4 ris style.

Product Information:
I'm really a fan of this Apex M4; It has the look and feel of a real SOPMOD M4, just a bit lighter and a MAJOR fraction of the cost, lol. Only thing I did so far was change out the foregrip for a stubby one. Also, I'm not sure why everyone's somplaining abouyt the flip up sights on these guns. Sure they're stiff at first, but if you mess with them for an hour straight like I did (I was really bored one day), they start to break in. 5/5


Just to be clear
this will work with a 11.1v battery?
