| My buddy just called me because he was caught off guard on the 6.8 forums. Apparently he was hassled for not using a bore guide. I have never heard of this but according to this guy nicking your barrel with a cleaning rod could cause a .5 moa defect. This doesn't make sense to me especially how a guide rod situated in place by the brush could do that. Sadly I'm not by a pc right now and am stuck on my phone so I can't get the full story. |
| The last several rods that I have bought have had a brass conical guide similar to THIS as part of the package. And yes, the crown is on the discharge end of the barrel |

First off no one "hassled" your buddy on 6.8Forum they were simply giving him advice that he asked for to take or not it's up to him. Second you can damage your barrel with a cleaning rod but there are nylon coated rods that IMO are safer to use without a bore guide. And lastly a lot of people never use a bore guide and their AR shoots just fine. |

damn took me awhile to respond, just got back in town. anyways I don't see the point of this guide rod, when the brush is in the bore its not like the rods scratching and dinging the shit out of the barrel.... am I missing the point? The 2 critical areas of a barrel for precision work is the crown and the throat/lead. Any damage to the crown can result in poor groups and flyers, that's why it's almost always recommended that you clean from the breech. Any nicks in the crown causes a slight disruption in the gas flow from around the bullet as it leaves the barrel, causing it to be less than stable. When you jam a cleaning rod into the chamber of a barrel, ideally you want it to be as close to in-line with the bore as possible. The edge of a brush or cleaning jag continually bumping against can wear against this area and cause premature barrel wear. That is why a bore guide is recommended and a 1 piece cleaning rod to minimize the amount of areas that can scrape into this area. What does this mean for a run of the mill blaster or run and gun setup? Maybe not much of anything but if you want to take the best care of your barrel and ensure a longer barrel life-you use a bore guide in an AR and clean from the breech. Call any barrel maker or gunsmith and they'll tell you that more rifles/barrels are ruined by improper cleaning methods more than actual round count. CDTracing, I shot expert multiple times with an M16 at 500yds as well, but crappy miltary ammo out of a loosey-goosey M16 does not make a precision rifle. I also wouldn't call the Marine cleaning method the correct way by a long shot judging on how I've seen Marines clean weapons. |

He was just concerned he had been doing things wrong for all these years. |

Lawman, you are correct about how we cleaned the M16's back then, and most likely they still do. I now take a lot more care on how I do it now since I am the one who payed for the weapons I now shoot. Using the tip of the firing pin with a patch to clean the crown of the barrel comes to mind, lol. |
