Went to the range today and put a few hundred rounds through my AR. I set it down on the bench for a few minutes while I shot my Glock 19. At about this time, it started sprinkling just a bit. I didn't think much of it until I picked up my rifle and noticed SIX water drops on the upper AND lower recievers! do I need to strip and re-finish the gun? What should I do?! I'd take pictures but I'm too embarassed to. Halp me, WMD!
