The A&K MASADA is a truly unique airsoft rifle. Not only does it look amazing, it also performs flawlessly on the field. The gun features a CNC Aluminum upper receiver and polymer body and stock. It has a side folding retractable stock which also has an adjustable cheek rest. The lower receiver is made of a durable polymer with a finely textured grip, giving it a very comfortable feel when you hold it. The CNC Aluminum upper receiver features authentic Magpul trademarks and a holographic Magpul sticker. A full sized rail runs along the entire top of the gun making it easy to add optics and other accessories. The front sight flips down and the rear sight is completely removable. The gun also has a locking bolt and ambidextrous bolt release, making it easy to adjust the hop up. A unique feature of the A&K Masada is that it has a quick change barrel system, allowing the barrel to be detached and re-attached with the turn of a lever. A 300 round high capacity Magpul P-Mag is also included. Battery and charger are NOT included.
