I have an m4 a3 with a 16" barrel and an A2 suppressor. What is the best way to plug the muzzel in order to leave copper solvent soaking in the barrel overnight? Thanks. |

You also have to plug the gas port if you want the whole length of the barrel to soak. Trying to plug the bore and soak completely is going to be messy, real messy. Personally, I recommend NOT doing that. Just swab with some wet patches and let that be enough to soak overnight, but only do this *according to label directions on the solvent of choice.* |
| Be very careful soaking as many copper solvents will harm the steel if left in to long! Butches Bore shine, Tetra Copper solvent and Sweets 7.62(used with extreem care) will get all copper out of the barrel with in 15 minutes. You might have to do it twice to get all but it will work and does not take over night. |

Try wipeout or similar copper solvent foam. Wipe out has no amonia so it is safe to leave overnight. I simply put a wadded up paper towel in the action (bolt removed) and spray from the muzzle end. Let sit overnight and run patches through the next day. Works like a champ Chris |
I assume that you mean Hoppes Benchrest Copper Solvent? Just follow the directions on the label. It works. Clean until you don't get any green, then run a wet patch through, leave overnight, then clean again until no more green/blue on patches. |

Thanks for the input. I have been using Pro-Shot Products Copper Solvent IV. It is semi-viscous so I ended up just swabbing the bore real well and letting it soak for a half an hour. Seemed to work pretty well. Just trying to maximize accuracy for hunting season. Starts next Saturday!!!!  |
Yes, ammonia will attack the chrome lining (if your barrel is chrome lined). Someone on here gave a very convincing argument that it really took some effort to get this to happen, but i certainly don't want to take the chance. Instead, it was recommended NOT to let the stuff sit in the barrel. I use Sweet's. When I decopper my chromies I just run a swab good to get it all around. Wait just a few moments... not long at all. Run a dry patch. Do again if I'm getting lots of blue. Then when I'm done, I douse a couple patches with rubbing alcohol and run them through making sure to get plenty in. This will deactivate the ammonia. I decopper after a new barrel has 3 or 4 hundred rounds. Then after that, probably every 1K or so. Once again, maybe sooner if the barrel looks like it needs it or I see some declines in accuracy. Gundraw |
I have heard this too. I will only let the solvent sit in the barrel for 10-15 minutes, tops. Then I will run copius amounts of dry patches through until a) the barrel is devoid of all solvent, b) the barrel is devoid of all fouling. Sometimes I do have to run more than one "wet" patch through to get all the fouling out. |
