This is all quite normal and the mudder has it right, the parkerizing and stuff all has a kind of Nap. I received six complete guns and ten uppers just before Christmas and they all have that gritty feel, lube them up and shoot'em, they'll smooth up better than greased lighting. We were shooting out in below zero weather after Christmas and the wheel bearing grease I usually use on the Carrier rails and on the bolt (inside of the carrier) and cam pin, was so stiff the guns were short cycling, this because we used the normal stuff (yes it's what we had at the moment and I knew better than to use it but hey, we were in a hurry for a little group therapy). We returned to the shop, degreased everything and re-lubed with a Full Synthetic bearing grease (note full synthetic oils will pour at 90+ below, whereas 10 weight wont take a nail with a hammer through the side of a can at these tempts and don't bother with the stuff with teflon in it. Go to your auto parts house for these super-lubes. You might try the synthetic really-really heavy gear lube too.. ) and bingo, no more short cycling in -17 below..t
