I Am Coming Out: 308 Subsonic AR10 vs AR15 300 Blackout 200gr Hornady ELD-X

Why not just go with AR10 308 Subsonic many have asked me. I have received so much criticism about 300Blackout being a waste of time. I just decided to show everyone on video one of the reasons why 308Subsonic is not for me. It will not cycle my rifle, I am sure I can get an adjustable gas plug and get very close to 100percent reliability.
