I recently picked up a Remington 7615 Police carbine that is shooting really well. I put a 3x9 Leupold VXII and a 2lb Timney trigger spring in it, and it is shooting .5-.7" groups with several brands of 50-55gr ammo. Since I really like this little rifle for general ranch use and plan to do some predator calling with it, I want to upgrade the finish to something tougher. I haven't had great luck with the remington matte finish not rusting on other guns I have owned and treated similar to the way this one will get used. Excessive oiling collects huge amounts of dust in my ranch truck. I have looked at the various finishes that can be dipped or baked on, but what is the best for long-term reliability through heavy use? The way this gun is shooting, I'd be willing to send it somewhere and spend a little to make it more weather and rust resistant. Thanks for the help.
