Today I was shooting my a17 and noticed it bump firing! Sometimes it would shoot two rounds, and others it would empty the magazine with one pull. Also it would shoot one shot, then while letting off the trigger it would fire a round. Has anyone else had issues like this? I purchased the rifle brandnew, and have put a couple hundred rounds through it. Sometimes it shoots fine, and others it is very unreliable or unsafe. Any input on what I should do would be greatly appreciated.
