Gamo With rusty barrel

[Flyboy73]

I saw about the Gamo rifle recall and went to the safe to check mine. Mine was made in 05 and i got it early 06 and not the recall list. I had mounted the scope on it but had not sighted it in, so its been sitting in the safe for a while.
Thought i would bore sight it. but the bore sight was not long enough with the plastic grip on the front of the barrel. Well when i pulled the bore sighter out it had rust residure on it.

Well i then checked the barrel full of Rust!!!!!!!!!!

Spent the next hour cleaning the barrel , but the receiver hole (where the air comes into the barrel)still is not that clean, not sure ohow to clean it real good with taking the whole gun apart.

I had not put any gun oil it when i put it away The manuel says use no lubercating oils in the barrel. Not sure if gun oil is considered lubercating oil.

But after closing the barrel and dry firing iti sprayed Rust sheath down the barrel.

Has anyone had this problem and how do you keep it from rusting.

If you are very concerned about having oil in the barrel, I would oil it with 1-2 oily rags before I put it away. The next time you go to shoot I would run a dry patch or two through the bore of the rifle. I have fired my Crosman RM377 with a light coat of oil with no problem.

Anytime you store a steel without any kind of oily oil or preservative, it is just a matter of time beofre the steel will start to rust. Sometimes it is a week or sometimes months. I found a light surface rust on my Crosman one time even though I oiled it. Light 000 steel wool and a little bit of oil and light rubbing fixed it.

I am not worried about useing oils in it. I just wonder why Gamo recommends agnist it if the barrell will rust without some oil.

Because believe it or not, there is a chance of the oil combusting when fired.
The following is not the best source, but it's the only one I could find.

Modern air gun lubricants (such as molybdenum disulfide) are generally designed so that they do not combust at the airgun's operating temperature. Before the availability of synthetic lubricants, when petroleum based products were used, upwards of 30% of the energy of the shot may have come from the burning or "dieseling" of some of the lubricant, according to some writers[citation needed]. The use of such combustible lubricants in modern guns, which are much more highly stressed, can severely damage the spring and piston seals
