Apex Fast Attack RIS M4 Carbine AEG Airsoft Rifle (Metal/Option)

[34871 / AP0004]


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.

Product Information:
My friends all play airsoft so I got this so i can join them when i have time. I don't know alot, but it feels pretty good when I pick it up. I also grabbed the suppressor for it thats like 20$ and it screwed on nice and makes it change the sound, not quiet but cooler sounding like bassy. May just get more into this if all the gear is as cool as this gun.
