SPORTS is slap (mag), pull (CH), observe (watch for an ejected round), release (CH), tap (FA), shoot
That SPORTS is bullshit. I learned a different SPORTS (seek cover, place the weapon on safe and remove the magazine, observe the chamber, reinsert the magazine and chamber a round, tap the forward assist, sight in and attempt to fire) for remedial action, but that's an aside.
Tap, rack, bang is immediate action. The SPORTS you describe is just a really slow tap, rack, bang. If immediate action didn't fix it, do you do immediate action again? No, you go to remedial action. Get behind something solid, SAFE IT, unload and clear (meaning look at the chamber to make sure there's not a gummy bear in there or something stupid) with the bolt locked back, put a new magazine in (throw the old one in the dump pouch, it's dead until you have more time to look at it) slap the bolt release and WATCH IT CLOSE WITH A ROUND IN THERE, and then set your gat back to blat-blat and play ball.
Remember, if IA fails, go remedial. The definition of insanity is to do the same thing over and over and expect a different result. If tap-rack, bang didn't fix it (and by the way, tap rack bang means watching for ejection with your peripheral) then it's time for soemthing else, lest you tap-rack-bang your way into a bolt override or triple feed.
