I was cleaning my gun at work the other day since I have been carrying my ccw pistol on me all the time and keeping my 556 rifle in the car everywhere I go, paranoid maybe but I am going to give myself the chance to get home if dumb stuff happens, I work too close to Nashville not to. Anyway as I was cycling the slide the bolt is loud. I have oiled the bolt and carrier on all contact points that I can find and still it just sounds loud. I may just be over listening and being too picky, anyone have a 556 rifle and thinks the action is too loud when cycling by hand??
