There’s a reason that most people fire the famous Barrett M82 .50 cal sniper rifle using the set of attached legs.  It weighs 30 lbs and spans over 50 inches.  Of course, former Army Ranger sniper Ryan Cleckner has no need for assistance.  After being badgered all day at the range by the Texas Triggers crew, he finally showed off his skills by hitting a target at 1,000 yards away.  On his first try.  Standing up.
