I have a piston setup and GunSlick is fantastic on it and all my auto handguns. I used it first on a 25 y/o "calico" 1911 my Da and I built in the early '80's. All parts were out of Shotgun News and ran well untill a couple of years ago. Replacement link and barrel and the timing was GTG!As for the GunSlick in an AR, my SR-556/6.8 eats it up. So far no FTF's, feed issues or cycling issues. A light coat of GunSlick on all contact surfaces and she runs, and runs. On match ammo it's -MOA out to 200 yrds. After that start checking tables etc... For most else, hand loads included, should be no problem. Gunslick is one product I will always endorse.
