Really good upper


I bought one a while back and buying more now in stock! The inside is NiB and make the bcg ride real smooth. You almost don’t need any lubricants, but when you do oil it up, it rides like nothing else. I can feel the performance difference between mil spec, a few billet I have and the WMD NiB. The WMD operates the best. Use a chrome or NiB bcg. I have a cryptic coating one that works unbelievably smooth. I duracoat finish most of my ARs so raw just means I can choose a color lol
