About the FN FNX-45 Tactical Airsoft Pistol

The FNX-45 is a full size handgun packed full of features, making it one of the nicest replicas on the market.  First off, the gun is full size, the real gun is designed to hold 15 rounds of .45 ACP in it's detachable magazine.  The Airsoft version uses a detachable green gas magazine that holds 25 rounds of 6mm airsoft ammunition.  The gun comes configured to attach a mock suppressor out of the box.  The barrel is threaded and has a thread cover installed.  The sights are raised so that you can aim over the mock suppressor.  The gun also features a functioning safety and decocker.  The mil standard 1913 picatinny rail allows you to mount a variety of accessories.  Need a laser or flashlight for those night operations?  No problem, just mount it directly to the rail and you're ready to rock.  The gun has a beautiful dark earth finish, giving it a high end tactical look.  The grips are textured to give you a secure grip.  There are also licensed FN trademarks all over the gun to give it an authentic look.  All of the guns also have a unique serial number.  The slide has a removable plate that allows mounting of a micro red dot reflex sight.  It does not use a conventional picatinny rail mount, but rather the sight bolts directly onto the slide.  In the box the gun also includes an additional back strap for the pistol - this gives you the ability to adjust it for different size hands.  For maintenance, make sure to regularly clean your barrel to ensure that the gun is always performing in top notch condition.
