Smooth as butter - Battle Arms Development AR-15/AR-10 Enhanced Pivot/Takedown Pin Set

I highly recommend these to ease the frustration of any AR platform rifle. Whatever magic that they put into these things makes them slide like melting butter resulting in nearly zero effort to get your AR apart. All that and still doing their basic job of keeping everything secure. These are one of those products that is a tad pricey for a good reason.
