Damn that sucks j4, I hate it when thinks do not work.. O.K. Sniper69 just passed through here and checked my .45 AR I was having stovepipe problems with. Damn it was not seating the rounds all the way. Upon trying to eject manually it was stove piping.
Now having no 0 patience with things that do not work, Sniper told me to calm down and do not try to set the world record toss with an AR. As I already hold the world record with heaving a non working AK 127 feet 11 inches. I like to use the Olympic move a triple spin and a friggen heave, timing is crucial.
Sniper told me to calm down and 90% of the time it is magazines to check first. Well be damned if my Bro did not call it. Bolt was dragging on the Pro Mag just enough to not let the round seat. Took some brillo and smoothed it down a bit. Oh hell yeah it did the trick..
Take your time, study what is going on. Usually it is something minor.. Let us know what yah find was the problem.
