Forty-Nine sons and daughters are never coming home...
Over-the-top gun fanatics (not reasonable & responsible gun owners) are caught up on semantics when 49 loved ones are not coming home - 49 lives not lived, 49 lifetimes of opportunities not explored, countless joys not experienced & life dreams not realized. These angry internet trolls are stuck on the distinction of how a round enters the chamber - by "direct impingement" or "gas piston”. The necessary fact remains… they enter the chamber basically at the same rate of speed. The terrifying & pertinent fact is how fast the shooter can discharge them. ANSWER: as fast as he/she can repeatedly squeeze their murderous trigger finger. The issue that the Nation is debating right now is Semi-Automatic Assault Weapons - of which, both the AR-15 & the Sig Sauer MCX, happen to be.
