The KWA LM4 PTR has been engineered by KWA to answer many of the short comings of the previous airsoft GBBR M4s. KWA spent many years in R&D for this gun so that it would be the most effective and efficient M4 GBBR right out of the box. Their goal was to make a gun that didn't need to be upgraded, did they succeed? That's up to you to decide for yourself, hopefully our video helps. On right you'll find Daniel from the Airsoft GI sales floor talking about his experience using the Lancer Tactical MK18 at Tac City South CQB Field.
