I don't have the parts entirely that I would need to assemble my lower, as somebody who does work with CNC and Lathes, you can tell this product is well built. I did notice a slight over mill in one of the stock adjustment holes, but nothing that would be seen or in anyway effect the functionality of this product.
Great kit and the h2 buffer I received is exactly what my build was needing.
Flawless performance
Solid product, shipped well.
Great quality product.
Fast shipping and will definitely buy from again.
Purchased this kit new at a local shop. When mating the buffer tube to my Noveske lower it would not index properly, either threading too tight against the buffer's captive detent or not far enough, rendering the detent dangerously loose. Pulled an old mil-spec tube out of my parts bin and it threaded on as expected. Additionally the castle nut provided with this kit would not allow my wrench to fit. Again, pulled an old castle nut out of my parts bin and it worked fine. Love BCM's products but would not purchase this kit again.
Typical bcm craftsmanship that we have come to expect.
High quality pieces for a solid build.
