I have handguns, pistols and revolvers in many calibers. Shotguns, 12 to 20 gauge and lots of rimfires but Ive never owned a center fire rifle. Ive come to that point in life that I have decided that I want a centerfire rife. Ill leave the need vs want debate for another time. I think I want an AR. I was looking at a buddies DPMS and another friends Hi-Standard, both seem to be good starter ARs. Heres the question, in the back of the DPMS manual there is a paragraph about breaking the gun in and it says to take a shot and then run a patch through the barrel and to do this for (I forgot the exact number) for the first 100 to 150 rounds. I then went to the Hi-Standard manual and there is no mention of this procedure. Wanna kill these ads? We can help!
