The McMillan M40A3 is the standard sniper platform used by the United States Marine Corps, and this is a 1:1 scale replica that is fully licensed. It offers many features that can also be found on the real gun. It is manufactured with a full metal barrel and a durable polymer body.  The cheek rest is adjustable to different heights, so any user can quickly and easily sight in and acquire their target.  A standard picatinny rail is built into the top of the gun which allows for easy installation of most optics.  A bipod adapter is also supplied with the gun.  It shoots at an impressive 426 FPS right out of the box, and the bolt on this gun is surprisingly easy to pull back, even with the powerful spring inside the gun.  The smooth re-cocking of the rifle makes it easy to stay on target when you preparing your next shot.  

If you want an airsoft rifle that is versatile, accurate, and easy to use right out of the box, then this will be a good fit for you.
