There are many videos online about airsoft giving good foundation training for real guns and in this case T.Rex Arms is making the case for such. The Real Deal Airsoft gives his reaction to Lucas' points which basically is an affirmation of such... "If your involved in the #airsoft and real firearm community, then you probably heard that Lucas from T REX ARMS, recently played at the Milsim op called Iron Horse lll by American Milsim. I am a huge fan of Lucas due to his training technique and philosophies."
