Corrosion X in bore and chamber

Uh oh... did I mess up?

Yesterday I was out with my M&P 15 (the standard model with the carrying handle). Since I hadn't cleaned it after the last few uses, I went ahead and did a (for me) thorough cleaning.

The last time I cleaned it, I used the Corrosion X for guns and this time all the fouling just wiped right off.

So, again I applied a generous dose of corrosion X to the BCG inside and out, and all moving parts in both the upper and lower receivers. I saw that my M4 feed ramps had some wear so I put a drop of Corrosion X on each ramp as well. Yeah, I probably used more Corrosion X than I needed too...

I have an extra bore snake and I doused it ( only the part where the embedded wire brushes are) with Corrosion X and ran it down through the chamber/bore of the gun. Didn't think anything of it at the time - I looked down the bore and it sure was clean!

Yesterday I read that lubing the chamber/bore can result in extra stress on the bolt since, apparently, the case of the round cannot grab hold of the walls of the chamber.

Not sure I understand this exactly, but now I am worried that I may have messed up. Do I need to swab out the film of Corrosion X from by bore/chamber? What would I use to do that - Hoppe's #9 solvent on a patch?

Or am I making a big deal out of nothing?

Thanks guys!

For longer term storage, I put a thin film of lube in the chamber, bore, BCG, etc. Use whatever lube you want. I use Ballistol. Before I go to the range, I remove all the excess lube from the chamber & bore. To do this, I pull a couple dry patches down the bore. I'll use a rod with a patch tip holder, put a dry patch on it, and twirl it around the chamber.

The reason you want to remove excess lube from the chamber and bore is because excess lube has the potential to cause a pressure spike leading to a kaboom. Since you're using a bore snake, applying lube to only the portion with the bristle, you shouldn't have a big issue. The section of the bore snake that is dry should pick up the excess lube.

If you really want to have a great set of tools to clean your bore, get yourself an Otis 5.56/223 cleaning kit. There are also other tools in a cleaning tool thread in this sub-forum.

Thanks, this helps a lot.

I have two bore snakes - one that I have the Corrosion X on and then another dry one (it may have had Remoil on it at some point in time - it's dry now). I pulled the dry snake through the bore a few times just to be safe.

I'll check out that Otis kit too ;)
 
I have a new M&P AR that I just cleaned and lubed ( it has yet to be fired Im doing that this weds) and I noticed this morning that there is a light coating of lube that I used now in the chamber. Is this normal or should it be wiped out and did I use to much? I feel as though I did not but I assume it came from the other parts where I applied lube.
 
I have been using Kroil lately to clean the bore and bolt group of my MP-15, along with a few drops of BreakFree in the lower.

Cheers,

Wipe it out.

Normally before I shoot (anything),I run a brush & Hoppes #9 in the barrel a few times,then dry patch until the patch is clean. I'll also use a "fatter" patch to make sure the chamber is cleaned of any "run-over" and one more up the barrel just to check any run over there again. Takes about 5 minutes and makes me feel better.

They can be hard to find,but there is a bore brush made for .223/5.56 chambers. Doesn't hurt to have a couple.

One of the best things ever made was the Otis AR cleaning kit. A must for any range bag.

I also found one that covers 17 through 12 guage for my other weapons in the same size kit only the 12 guage brush is in its own little plastic bottle.
 
I know it sounds a little over kill. But I always check the breach & barrel before I start shooting. Who knows what/could/might/who knows how "IT" got into the barrel. A breach blast is not a good experience on any level. In the military and also as an EMT I saw some nasty injuries on the range and also some very lucky people that walked away from what could have been a disaster. Be Safe.

Patches drive me nuts. What about putting some Hoppe's #9 solvent on my other bore snake and running that through once or twice?
