Have you tried the Slip 2000 grease with ARs?
yaaasss. That stuff is hot garbage.
One more I'll add is Rem-Oil. That stuff made my Glock feel crunchy, took a week of cleaning to get it all out and replace with my preferred Slip 2000/EWL30 (like many here). It's what was available at the work range one day when I qualified, and since that experience I simply choose to leave my gun dirty until I get home unless they have Slip 2000.
