In this video, Airsoft Alfonse got a Special Force guy to try out an airsoft gas blowback and airsoft bolt action sniper to see his reaction. This took place during an event hosted by MiR Tactical... "The KWA LM4D Professional Training Rifle is an ATF approved gas blowback replica available in the United States. It features a new hop up system that was developed for the LM4D 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 users to customize the configuration."
