| Well I was cleaning my AR laswt night really well and I happened to look down into the flash hider and saw a bunch of build up.... wasnt sure what it was but i used a pick and as the black soot was removed it was all copper build up on the flat front edge of the barrel. I had to use hoppes lead remover stuff and a pick to eventyually get it all off , was a bitc$ to get off. Does anyone else experience this... Could it affect accuracy cuzz it was right near the crown and I figured it could distort gas flow and stray the bullet if you know what I mean. I think I will be cleaning this spot every cleaning from now on |

I use Break-Free Bore Cleaning Foam on my rifles. It cleans the entire barrel from the locking lugs to the flash hider. It’ll soften that carbon build-up forming between your barrel and flash hider so that a q-tip and CLP is all that’s required to keep that area carbon free. Applied to the barrel: BF BCF at work in the FH.  After wiping away the BF BCF: A small amount of carbon remains. This can be wiped away with CLP and a q-tip.

What I've done recently when using BF foaming bore cleaner is after I've run a few patches through the barrel, I use canned air to blow out what is in the gas tube then run a pipe cleaner through the gas tube. Run one more patch through the bore and I'm done. |
