forzArmata Posted February 20, 2013 Share Posted February 20, 2013 (edited) I know you aren't supposed to lube the pistons on the M4s pistons, and I never have. But...I fu*king hate scraping the carbon off of them after a big range session, and Frog Lube helps in this situation by preventing carbon from adhering to the metal. So, although the manual says to not lube the pistons, what would be wrong with applying a bit of heat and a very light coating of Frog Lube, then wiping it off once soaked in? *If you are unsure how Frog Lube works or you have never used it, please either use it or research it before commenting. It is not like a standard gun oil, which the manual says not to use. The area of the pistons I'm referring to is circled: Thanks for the help!
