Solid Mount for AR style buffer tubes/ stocks

First off it is an form of alloy metal, but its definitely strong enough for the application. Threads and QD mounts are clean and machined well. You have two options when mounting the buffer tube into place. Does not have a standard endplate to keep it in place so you will need to do one of these to keep the buffer tube from moving around. No instructions with it, which I found weird. One is to drill a small hole through the bottom of the buffer tube and insert a tight slave pin through the bottom of the mount (mount is pre-drilled on the bottom) and into the buffer tube. The same way you would with a muzzle break. No need to weld if you used a tight pin.Second is use a castle nut and wedge it against the mount. Use Loctite thought so it does not work itself loose. Awesome adapter for the price!
