The KWA LM4 RIS Professional Training Rifle is an ATF approved gas blowback AR style rifle available in the United States.  It features the Type 3 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 RIS PTR buffer tube has the same diameter of a MilSpec 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 RIS PTR’s modular design allows limitless customization options to best suit the individual’s training needs.
