I have had possession of a relatively new (I'm 2nd owner) AR15 S&W and just had something occur the other day that is really rather disconcerting. After chambering a round (55 grain SP) I aimed the weapon downrange, and when nearly ready to fire, placed the safety from off, to 'fire." Without getting NEAR the trigger, the weapon discharged the round I had just chambered.
*** , eh? What causes this and how might I best fix THIS little problem that has caused me to shelf the darned thing until fixed...
