I decided to get an AR15. I always wanted one, and I found a good deal so I justified it. I bought a Bushmaster M4 with the flattop an 16" barrel. I put a Mueller 4x16x50 illuminated Mil dot scope on it. Does anyone have any experience with shooting these guns? I have heard there pretty accurate. I dont plan on shooting further then 250 yards. Thats about a max in my area.
