Thread: Lug and breech face cleaning for AR

Had a blokes look on uncle Google but didn't come up with much.

Are their any tools or tricks to cleaning the locking lugs and breech face of the AR?

I have a chamber brush with the stainless brush on it but it is not doing the job. She is starting to get a build up around the breech face and I cannot reach all of it.

Cheers in advance.

I've never felt the need for these, but you may find them helpful for what you're looking for. http://www.trademe.co.nz/1088744327

You can get proper brushes for the barrel extension but I've honestly never bothered to clean it.

Yep used them but not the best, they tend to fall off the end of the rod. @R93 I use a 12ga Snot Gun brush to clean the lugs and breach face, much better tan the chamber brush.

You must pick your nose a lot to keep you in ammo for that😆

Yeah I have a heap of 12 g brushes but they don't seem to get that bit on the outer breech face. Where the barrel meets the receiver.
Maybe I am just being fussy.

Maybe soak it a bit with some of the carbon killer stuff and have another go?

Probably just being fussy as it does not seem to build up much with use.
Tried gently with a dental pick but I can't reach from 4-8 o'clock.

Ha Ha Ha I am one of the worst for finding certain connotations in posts and that one didn't even register😆

Jeeze Dave I am sure you could be quoted as saying excessive cleaning is the death of most millitary rifles? (or maybe my memory has its wires crossed)

Shoot it till it stops working then clean it.....with a wire brush on a grinder

Yes I did say that and I stand by it as far critical moving parts and barrels are concerned.
My AR barrel has not seen a brush yet. Just wet and dry patches.

The area I want to clean is not critical to the action of mech, although it could if left, cause a stoppage. I can't afford a stoppage in a match.
So it is not going to wear from a clean every once in a while.

I've found that a paddle pop stick, sliced with a very sharp knife @ 30 odd degrees to a fine point, can really shift the muck. The wood isn't going to marr anything in there except the carbon buildup, and with a good squirt of ballistol a day before it all loosens up nicely.

Cheers Tommy, I will give that a go.

The reason escapes me, possibly something to with the boss coming home at 4.. and i suspect handcuffs are involved but obviously you should just do it before 4 or after 8.
