corrosion in barrel

[bountyhunter]

A good friend recently acquired a Colt 1911A1 marked US Govt and "Released British Govt 1952." It belonged to a friend of his who had been overseas a lot back in the day. The gun has been neglected for probably several decades. Rust was everywhere internally although the finish has held up really well. The slide looks great as does the frame for the most part, but corrosion had piled in making it difficult to remove the mag release and the safety and slide stop plungers were frozen in the plunger tube to the point that I broke two punches trying to get the plungers out and finally had to give and remove the tube. So that's no big deal, I can put in a new tube and plungers/spring easy enough and I think I'll have the gun back in good shape for him. All lugs look good, mechanically I think it's good to go.

The only thing I'm worried about is there is a fair amount of corrosion in the barrel.

The best thing I have found for removing light rust is auto chrome polish. It is designed to remove rust from mirror bright surfaces without clouding them so the abrasion level is extremely low. Get a nylon bore brush and go after it.
