White Lithium Grease?

 

There are a few different greases out there. I happen to use one by remington. The fine tipped applicator makes it easy to dispense in small amounts to rails. A little goes a long way. Cost was 5 bucks.

There are a few others out there. I just happened to add this one to my cart to get free shipping. I like it a lot. Try a tube or try another gun grease out. I bet you end up liking it more than oil for the rails. If you don't, it's only 5 bucks. Throw it out or give it to a buddy.

I use Militec oil and grease. Works well.

Magnalube-G is what I use, and is an excellent all-purpose PTFE containing grease. 1LB pint can is $16 shipped to your door from amazon. Will last a lifetime when used for guns. I use it sparingly in all high wear points.
