I'm doing a total strip down of the rifle in an effort to throughly give it a once over cleaning. I recently dug it out of the closet and haven't fired it in over 15 years, and best as I remember, I have never cleaned it, not even imagined I cleaned or thought about cleaning it. I was negligent to say the least. I bought it new in 1981 and I was young and ignorant and would always simply put it up after shooting it, never considering it should be cleaned from time to time. That was through the first 10 years of it's service to me, and the remainder to present day, well, it's been in the back of the closet! Now I want to give it what it deserves, and always take care of it. BTW, considering the abuse, it's in really great shape, very minimal light rust in a few spots and that's it! Lastly, as I re-assemble the rifle, should I use a firearm grease internally or simple gun lubricant? Thanks for any input.
