Hi all,
Shot my SGL-21yesterday for the first time and it was great. After field stripping it this morning I found some reddish-brown, rush-looking substance inside the gas block. I fired some Wolf from a friend yesterday and don't believe it was corrosive, but am wondering nevertheless if this is rust or just normal shooting residue. I did not find this residue anywhere else in the gun (just in the gas block) and my barrel patches came out with no reddish-brown on them. Pics below show a little remaining residue before I completed wiping it all out. I suspect this is not rust and is instead some sort of normal shooting residue but don't have enough AK-47 experience to know for sure. If anyone has some insight into this it would be appreciated, don't want to bust out the hot water or Windex unless it's necessary! Thanks, Jimmy

A little rust is possible anywhere you have a bit of humidity. I would just clean as normal and keep an eye on it. A little patch like that is nothing really to be going nuts over. Well thing is the pics were taken after I wiped most of the residue out of the gas block. Originally there was a ring of the stuff around the inside end of the gas block, and more of it on the end of the gas tube, the part that sits inside the gas block. So point is there was much more of it originally than the pics show. |
| Or it could be normal grease/lube from the assembly process. I noticed that my 107 that I had last year would "weep" a brown residue similar in color that looked almost like it could have been rust, but after asking about it on this board I was told not to worry; it's normal. I just kept cleaning as per usual with rem-oil and eventually I stopped seeing it. |

I'm suspecting this is not rust but some sort of residue. The rifle is new and the ammo was non-corrosive(?) Wolf. Would be interested to read more details per your original post, if you can find it. |

Just a tiny, tiny spot of surface rust. I be you can literally scrape it away with your fingernail. It happens, all the time. The preservative is a darker brown and seeps out between closely fitted parts, like between the gas block and the barrel, as an example. |

It was easy to clean out, all it took was a wipe or two with a patch + CLP. I field stripped and cleaned the rifle before firing it and the rust was not originally there. I still think it's weird that rust would have formed sometime in the one-week period between the first time I cleaned it & the day after I fired it. As far as I know the ammo was non-corrosive. Never had this prob with my AR-15. No biggie I guess, unless it happens often... |
