I was originally after the Daniel Defence Lite 9 rail to achieve the MK18 look, but it was out of stock so I bought this one instead based on what it says on the this site beautiful finishing. High recommended.
Although the finish IS pretty good, the delta ring supplied had no threading on the inside. Had I not had a delta ring of my own, I would have returned this item. It is also rather complicated and somewhat tricky to mount.
Having said all of that, once I got it on there properly, it felt solid and looked the part. I have yet to game it, but initial impressions are pretty good despite the difficulties.
I would recommend this item with a caution that it takes some fiddling around to get the right fit.
