The McMillan M40A5 is a standard sniper platform used by the United States Marine Corps.  This 1:1 scale replica is fully licensed and has many features also found on the real rifle.  It  has a full metal barrel assembly including bolt, barrel, trigger, and flash hider. The textured body is built from a durable yet lightweight polymer.  The stock design in combination with an adjustable cheek rest makes it easy for any user to quickly sight in and acquire their target.  A standard picatinny rail is built into the top of the gun allowing easy installation of most optics.  The gun shoots at an impressive 443 FPS right out of the box when using 0.20g BBs with Green Gas at room temperature. Because no heavy spring is required to pull back while operating the bolt, follow-up shots are extremely easy with this rifle in comparison to spring-powered versions. If you're looking to have a modern-day elite sniper rifle, the McMillan M40A5 is one of the best out there!
