Jonathan Higgs of Airsoftology is back at his studio for another Airsoftology Mondays episode. He has been flying to places visiting the recently held SHOT Show 2015 and also going to Hawaii to visit friends and airsoft shops. Now some interesting topics in this episode, and perhaps people may want to know more about GMR these days... "We answer your questions on non-M4 guns in 2015, SHOT Show admission requirements and the best ear protection for airsoft in this show."
