Maintenence oddity
 

Found something odd while cleaning my new AEG for the first time. K im still fairly new to this, but I cleaned my gun for its first time today and as I pulled out the cleaning rod out of the barrel there where some black shavings stuck to the end of the rod, wrapped around the cloth on the rod. At first I thought it was dead grass but when me and my friend checked closer it look like black plastic shavings, like off a BB. Kind of scared me and I was just wondering if anyone else found this junk inside of their barrel?? The whole reason I decided to clean my gun was because the accuracy gradually degraded and I assume its because of the little shavings inside (Well thats kinda obvious). Thanks in advance for helpful advise!

It's not too uncommon for there to be BB residue in a barrel. Shavings is a little odd however. Do you use black BBs? If not you should make sure it's not bits of hop up or your nozzle although I'm not sure how that would happen.

Yes I did use black bb's, this would of courses interfere with the accuracy right? I just want to be sure its not something else. Anyways thanks for such a fast reply!:D

Are you sure everything is aligned correctly(IE your hop up/barrel/barrel attachments)? Something seems to chaffing the bb, causing shavings, another possibility is using low quality/old bb's

Ok, ill have a look to see if everything is aligned. As for the bb's i'm using airsoft elite.2g bb's. Thanks again for all the help guys.:D

Ok a little update on my problem, I took the inner barrel completely out a few days ago to get a good look inside. After attempting to clean it a little bit I took a look inside the barrel and saw that the little shavings of bb's were still there. I also noticed that there was what looked like melted white/black plastic ALL over the inside of the barrel (possibly because a lubricant or something reacting with the bb plastic?). The barrel is a stock CA m15a2 barrel which I have only used a few times. Should I just scrap the CA barrel and go for a systema or prometheus barrel? Thanks for the help.

Get a new barrel.

get a new barrel, that one's not worth using anymore

How would you restore such a situation? im going through the same thing at the moment and im pleased with the accuracy it had until now. I would like to restore it and buy a new barrel. What would be a good method of removing the gunk and polishing? Ive put a strip of micro-fiber cloth the whole lenght of the barrel and spun it with a dremel with brasso but it gets pretty hot and still has the flakes stuck inside.

just buy a new barrel and scrap the old one. get prometheus. i used a systema tightbore and didn't think that much of it. it was so-so IMHO.

I believe that might be because systema barrels are crap, are they not? No QC on them for some reason?
