I'm one of those guys that tries all the newest Uber cool lubricants and cleaners. In a thread over on arfcom folks discussed using grease on the bolt as a lube. I stopped into a local pep boys and picked up a can of Mobile 1 synthetic wheel bearing grease. I pulled my bolts and lubed them using just a tiny amount that was stuck to the top of the can. I cycled the bolts and I can say it is super slick when hand cycling. I've been using grease on my pistol slides for years with no ill effect so this stuff should work well for that also. A small can was under $9.00 and will last a lifetime or two or three. Wanna kill these ads? We can help!
