While still active law enforcement, I attended a number of classes involving the AR platform. It was in these courses I first heard of using Mobile One synthetic oil to lube the AR bolt. Prior to that I was using CLP. I really didn't like CLP because it got all over my Bolle' goggles or glasses. I switched to Mobile One 15-50 synthetic and was sold on it, no more oil slung all over the place! I've been using it now for about 15 years on my AR's and my pistols without any problems. It stays where I put it.

"The strongest tactical move is always the one in which you reap the highest gain, at the lowest cost."
Tetra grease on rails and FP-10 on small moving parts, works for me, I did use gun butter on rails but found the Tetra adheres better with less mess.
I usually use Mili Tech grease on my semi auto rails and AR bolt & carriers and Mili Tech oil on the outside of my pistols and rifles except the wood and polymer parts of course.
