This M4 variant by Valken Tactical has the look, feel, and functionality of an effective CQB weapon. The built in aluminum mock suppressor give the gun a "special ops" look that you usually end up paying extra for with most airsoft rifles. A set of easy to deply flip up sights are included with the gun, making it a breeze to attach virtually any type of optic that may be desired. The stock can be adjusted to six different positions and also houses the battery of this airsoft gun. The grip is molded for a more secure and comfortable grip than a standard M4. The suppressor is removable giving the player the option to use this gun in an even more compact form. Internally the gun features a full metal version 2 gearbox and an anodized 300mm inner barrel with a 6.05mm inner diameter. The hop up is also full metal which is usually an aftermarket upgrade on most rifles in this price range. A 300 round high capacity magazine is included. To top it all off this gun is covered by a 1 year manufacurer's limited warranty.
