I'm using a Defense Solutions LLC mount on my SRS. Just got back from a long range shoot in South Dakota where I managed to get some hits on targets from 100 to 2500 yds using my NightForce 5--25 ATACR. The mount is a 70MOA and allowed me to use everything the scope had to get out there while still using a 100yd zero for the whole range of barrels I've got. I got hits on steel man size silhouettes out to 1500 yds with the 6.5 X 47, out to 2000 yds with the 7.5 X 55 Swiss and my buddy hit the 2600 yd plates with my rifle using the 33XC. I only made it to 2500 with that one.....too windy. Its a solid mount at a reasonable price made from one piece of 7075T6 on a 5 axis machine. They're hard anodized instead of standard anodizing or paint. My 34 mm scope fit perfect. I saw one of these mounts taken off an SRS zeroed with 6.5 X 47, dropped onto and used on a 223 AR and then put back on the original rifle, dialed to the original dope and fired for a first round hit at 1000yds. Pretty solid.....
Also saw another one used on an HTI in 375 Cheytac that ran the range from 1000yds to 3520 yds (2 miles). I'd take it over a Spuhr anytime.
Had a great time with my SRS out there in South Dakota for the week. Did a lot of shooting and hit some steel I couldn't see very well without the scope.
