According to the arm. I lube my rails before shooting as well as pivot points like the hammer/trigger/sear/and barrel bushing/lock. Same for rifles. I run a clean patch through the bores, wipe the bolt faces, and feed ramps. On operating rods with rollers or slide areas I give them a little extra. Try never to have oil that you can "feel" or wipe off with your finger. When storing I give them a great coating of Rusty Duck, Remoil, CLP, or something similiar on all moving parts and in the bore. I store them upside down to keep excess oil out of the stock. Really am ashamed for allowing my old 742 carbine to get rusty. It got some moisture in a horizontal storage hidey hole and made a mess. Have it soaking in oil and have most of the rust off. Will have to re-blue--well will probably get it Parkerized and redo the stock/forearm. I like that dull finish on shooters.
