cleaning barrel


January 25, 2004, 01:58 PM
Was just looking through my Sig manual and it states to never clean barrel from muzzle end.I have always cleaned all my barrels from the breach by pushing brush all the way through and then pulling back through.Should I not be pulling it back through muzzle end like a AR-15?

While I am no expert, it seems that not cleaning the barrel from the muzzle end is SOP. I have heard that it is because the rod rubbing on the muzzle will wear the muzzle and affect accuracy. IF that is true, how does an aluminum rod wear a steel barrel? There must be more to this issue.

I could be wrong, but I believe the bigger issue is to avoid pushing any junk back into the action of the weapon. There's enough crud that already works its way in there without shoving more into it to gum up the works. By pushing or pulling from the breech toward the muzzle, any metal bits or gunk will ideally go out the muzzle.

I was told this as well. I think they say this because if you dont get the brush right on center and then push it in it may rub one side of the front of the barrel. I guess after several times you do this it could wear down part of the front of the barrel and reduce accuracy? Thats just my guess, but I have been known to be WAY off:)

Breech to muzzle, recommended to protect crown from damage and pushing gunk back into action.

Use a muzzle guard if have to go from muzzle ...or use a OTIS pull through system, especially for revolvers and lever actions where one cannot remove bbl, or gain access like on a bolt where a bolt guide is recommended.

If you can find some in your area, try Sweet's 7.62 copper fouling remover. Works like prunes through a duck!

starting at the muzzelend can cause small (almost micrscopic) scratches to the crown wich can affect the accuracy. It wont cause enough damage to completly miss your target but if your into competiton shooting it could eventully cause a enough of a problem to be of concern. It also helps to keep deposits out of the action.

"prunes through a duck!"

I've never had a problem with this.

I agree, the crown could be marred if the person cleaning dosen't know what the heck they are doing.
