Vipex Airsoft got some nice things to say about the KWA LM4 Gas Blowback Rifle in this video review... "In this video we’re going to go over the KWA LM4 GBB. It’s been a fun gun to shoot and definitely add so much more realism to playing Airsoft. I’ll be going over the guns build how it compares to a real M4 and some basic maintenance."
