Another "is this usual" question
I took my DD M4V3 out the other day and found the selector switch was having a hard time going from fire to safe with the bolt locked to the rear. It would go, but about halfway through the switch, the selector encountered good resistance. It wasn't a problem as long as the bolt wasn't locked back and went through smoothly if it was forward.
Specs: Daniel Defense M4V3, approx 200 rounds through.
Is this a normal problem (or even normal for that model) or something I should contact DD about?
