Most of you probably know what I am fixing to explain, but it helps descripe the problem I am having and what I need to fix it.

I use Larue Tactical's quick detach scope mount on two of my rifles. This allows me to purchase one scope and switch it back and forth between rifles very easily without losing my zero.

The two rifles I use the QD mount on is the DPMS LR308 and the Savage 111 in 338 Lapua. The only downside to this method is that you have to adjust the tightness of the Larue QD levers if the thickness of the cross slots on one picatinny rail base differs much from the other. But if the thickness of the cross slots are the same on both of your picatinny rails, switching out optics is a breeze and no adjustment is necessary.

Since I cant really replace the flat top rail on the DPMS, I have to match it with the base I install on the Savage 111. I currently use a EGW HD picatinny rail scope mount on the Savage 111, but the thickness of the cross slots does not match the DPMS and requires me to adjust the levers each time I change optics.

The picatinny rail scope mounts I have seen on the internet dont have the specs listed regarding the actual thickness of the cross slots. I have measured the thickness of the DPMS cross slots and just need to match it with another picatinny rail. I dont have the measurements on me at this moment but will post them a little later.

Am I overlooking something here, or do product descriptions not usually list that measurement? Any advice would be great..
 
Perhaps you should contact DPMS and see if they make or outsource their rail. If they make there own, see if they can make one or let you know what company they outsource from. Just a thought! It beats trying to get a bunch of rails to see which one is going to work for you. Good luck
 
What you may need to do is take your DPMS and the rail from your Savage to a good machinist and have them machine the Savage base to match the dimensions of the rail on your DPMS. Short of that, I don't believe you'll find anyone making a rail specifically matched to the DPMS. In order for this to work, the Savage rail needs to be larger than the one on your DPMS, I don't know if that is the case or not.
