Hi guys,
We have corresponded about this Noveske upper before, a 12.5in stainless steel Crusader barrel with the Switchblock, and their 9.5in rail. 
It is the heaviest 12.5in upper I have ever used, but it is EXTREMELY accurate. At first I thought the culprit was the medium contour SS barrel alone, but I now believe that the rail is a big part of the problem. My research shows that the rail by itself is at least 13.5 oz, and the big ass steel barrel nut is 5 oz!!! That's allmost 20 oz for rail & nut alone!!!!! The barrel and SB are 29oz. I believe that we can make this upper lighter by switching to another rail, either a DD Omega X Rail 12FSP (13oz with the rail trimmed back 1.5in in front to accomodate the 12.5in barrel), or the DD Mk18 RIS II (13.5 oz , with a space routed thru the top half to allow access to the SB), like this... 
Both of these rails are two-piece, which allows for an easier install of the Switchblock. Which of the required mods would be easiest for you to do? I like the Mk18 rail more, but the goal here is weight savings. Let me know before I change my mind and dump this upper. Regards, Jorge |

We can do either one. OK, then three logistical considerations: 1) Do you have the SWS nut wrench to take the big nut off? (SWS sells them for $30) Maybe a strap wrench will do. 2) Rail mods are not listed in the Services page. Where do I input the request? 3) How easy is it to get the DD Mk18 rail? |
