I have a trigger problem (I think) and rather than create a similar looking post (and with coyoteseeker's permission) I'll ask it here.
I have fired a couple hundred rounds out of my new semi-auto .223 rifle. Out of those 200 or so rounds I have had 3 or four shots fired where two rounds were fired with one trigger pull. Although two round bursts aren't necessarily a bad thing I would rather have more control over my weapon than that. Any ideas as to what might be wrong or the cost I would be looking at getting it taken care of?
