Did you buy the gun as the picture shows or did you add items to it? I can understand somewhat about not firing the gun, as you have so many. I have a couple in my safe that I haven't fired either. I just have other things to do or see something else I want, so put it aside. I have work to do on a couple guns,(just minor things), & I keep putting that aside too.
Why the picture of the AR15 with a bayonet? In Nam I never had to put my bayonet on my M16,I just didn't get close enough for that, but close enough to shoot.
