Very well made. It hooks up to the muzzle device I made awesome. I would recommend this to anyone who is looking for a stainless Steel end cap adapter.

I wish I had found this sooner. The end cap is well made. I would like it more if the threads were a little longer even though there is more than enough for a solid hold. Thank you
