I am able to find very little information relative to smoothing and adjusting the trigger pull of the M4. The trigger on my DD M4 is a relatively crisp single stage trigger but too heavy and could be cleaned up some.
It seems most people would rather drop in a better trigger, but before I do that, I would rather play with what I have. Can anyone point me in a direction where someone shows how to clean up the M4 trigger pull?
Thanks and best wishes.
