What are you upstanding citizens using to clean and lube your AR 15 rifles? I decided to use Frog Lube since I'm using it to lube and clean my Sig P226. The Sig armorers and my local gunsmith recommended frog lube to both clean and lube by P226. I'm assuming that Frog Lube will work for my POF P415 as well so when I first got the rifle, I broke it down and wiped clean the the BCG, barrel, chamber/ramp and what not and then applied frog lube and also did the same thing after shooting 120 rounds. For what its worth, I fired 120 rounds of mixed PMC XTAC 5.56, Remington .226 and Wolf steel case ammo..I also mixed and matched the different ammo in the same mag. All ran without a glitch, even the Wolf steel case ammo. Not sure if that's just a matter of luck, the POF P415 or frog lube.
