KWA LM4 PTR Full Metal FV Gas Blowback Airsoft Rifle
The AR15 was originally designed as part of the U.S. military's initiative to develop a lighter smaller caliber weapon as the standard infantry rifle. This innovative weapon utilized aircraft technology to lighten the rifle's overall weight.  This led to the creation of the M16 which has served as the backbone of the U.S. Military for more than 40 years.  Since its inception shorter variations of the M16 were developed for the US Special Forces and other branches of the military, such as the M4A1.The KWA LM4 Professional Training Rifle is an ATF approved gas blowback AR style rifle available in the United States.  It features a new hop up system that was developed for the LM4 to improve range performance on the field.  An aluminum alloy receiver houses the full steel reinforced bolt carrier for strong reliable feedback.  The LM4 PTR buffer tube has the same diameter of a MilSpec Butt Stock which allows operators to customize to their weapon configuration.  In addition, the lower receiver can accept aftermarket AR15 pistol grips and trigger guards.  Other details such as the operational forward assist and bolt catch feature provides the user unparalleled realism by mimicking fundamental AR15 weapon manipulation. Similar to real AR15 style rifles the LM4 PTR's modular design allows limitless customization options to best suit the individual's training needs.Rate of fire: 13+ RPSVelocity: 110-116 MPS [360-380 FPS]Energy Output with 0.20g BB: 1.02 JoulesPropellant: Green GasGas System: Force VelocityMagazine Capacity: 40 rounds
