Hi All,
I am cleaning my AR15 for the first time using the M-Pro 7 kit from Bownells and the bore brush has separated from it's threaded base about 6-7 inches from the muzzle. I only have experience with shotguns and I am reluctant to try and push it back towards the receiver as the manual says this is a no-no. Before I bring it into to the local gunsmith is there anything I can try before giving up? BTW, the brush seemed a little stiff, as it is new, but gave no indication that it was going to seize up that way. Thanks, Darryl |

Lost a great day at the range, but at least I found this great resource. Many thanks for your quick responses and help. Darryl |

Darryl If you take a look at the bore with a good bore scope, may very well see the damage ... however .... you best option is to only use quality brushes with out steel wire centers and inspection each one before using. |

I seriously doubt this. |

I seriously doubt this. No, not suggesting the bristles of the brass brush damaged the barrel. My two concerns (which may at most be worth the electricity used to down load them ;-) are: 1: IF a rifle bore is damaged, you may very well not see it with out a bore scope. However, as a side note, for the accuracy many expected/get from an AR-15 shooting generic FMJ ammo off hand, rapid fire - a little damage to the bore (away from either end) may not be a major factor. 2: My concern for damage to the bore would be mostly from contact by the center mounting hardware (on some brushes this is steel). While the chrome is fairly hard, with point contact pressure (i.e. edge of a sheared center twisted steel wire) one could run the risk of damaging the thin plating vs. classic abrasion wear. |

This topic got me thinking
My Hopps .22 cal bore brushes only go down the bore of my rifle with a good deal of force. Is this normal for small bored rifles? I am use to .30 cal rifles and when cleaning them with the appropriate sized bore brush it does not take near as much force. I also use have problems with patches but I was able to fix that by just cutting them smaller. |

Just to update. Rifle is firing well. I've run 100 rounds through and using the iron sights I've been able to keep a 2-2 1/2 group size at 50 yards, which for me is good. Fired 40 rounds at 100 and they were all reasonable close to the center of the paper, certainly close enough to do their job. Thanks for all of your help. There has been no problems since I switched to a bore brush that hooks onto the shank rather than pressed on. Be Well, Darryl |
