[QUOTE="bookworm, post: 287095, member: 13840"] I've been trying to figure out why I can't get my AR-15 to shoot. Basically the best 5 shot group I can muster is around 3". I posted about it here a couple months ago: [URL]http://www.longrangehunting.com/forums/f19/ar-15-accuracy-help-40596/[/URL] The more I read the more I see that "everyone" with an AR-15 seems to get pretty good accuracy (< 1 moa). I have access to a boresope at work, so I decided to take a closer look at the barrel to see if anything jumped out at me. I didn't find anything inside the barrel that stood out (although I'm no professional), but below is what the crown looks like. Now again I'm no gunsmith, but this crown looks like a rat chewed on it. I don't know exactly what a "good" crown should look like, but can I assume that this is not it? Do you think that this could be my source of inaccuracy?
