The PM vises—and they have a couple, will work great for stock inletting. An AR police armored told me that a Kurt vise is sturdier for machining metal. I don’t see how the PM 4” would have any issues with metal though. The PM clamping set has worked great for me as has the ultra precision chuck. Matt is very focused on quality and will shoot straight with you. I found I needed a couple of v-blocks, an angle plate, some parallels, edge finders, etc.
