G&P is well known for making durable, high quality electric rifles and this AEG is no exception.  Externally it is extremely solid with virtually zero wobble anywhere on the gun.  The entire gun is made of metal with a Knight's Armament URX 3.1" Rail system installed on the front.  The URX rail system is lightweight and adds a unique look to the gun.  It even comes complete with rail covers and a forward hand stop.  The rail system allows the attachment of tactical accessories such as scopes, sights, lasers, flashlights, and foregrips.  A QD sling attachment point is built into both sides of the rail system, bringing the total sing attachment points to 6 on this AEG!  Fully licensed Knight's Armament trademarks also both sides of the lower receiver which gives the gun a more authentic look.  Removable Knight's style flip up sights come standard on this AEG.  They are easy to remove of flip down if the use of optics is desired.  Internally the gun is built like a tank.  With strong steel gears and a full metal gearbox, this this gun can handle the stress of any situation you may find yourself in on the field.  The G&P motor provides impressive torque and quick trigger response.  We tested this gun to shoot at 395 FPS with 0.20g BBs, at a rate of 16 rounds per second, with a 9.6v battery. The official SR-16 Knight's Armament Co trademarks are laser engraved on the full metal lover receiver to add the finishing touches to this excellent high end airsoft rifle.

Battery and charger are sold separately.  We recommend a 9.6v nunchuck battery.

Please note:  this gun comes with a Deans connector installed.  Standard Tamiya connectors are not compatible!  An adapter or conversion is required.

For your convenience, we offer a Deans battery conversion service.  Sets of deans plugs can also be purchased here if you'd rather install them yourself.
