Very simply, my brain is tilted about 10 degrees or so. Probably not installed properly in my skull or whatever. Bottom line, I cannot line-up a freaking rifle scope horizontally. Or vertically for that matter. Sometimes my scopes are mounted with such a tilt I can see that the top of the elevation turret is sitting wonkie. Even knowing about this inability I cannot accurately compensate for it, I am tilted big time. Of course my gun-magician buddy simply holds the rifle outward, grabs the scope for three seconds and starts tightening the screws on the rings. He does a perfect job, accurate to 00001" every frigging time. When he looks through a scope I have mounted one of his feet raises off the ground as he tries to get squared away. Now all is not competely hopeless because there are a couple of tools on the market that give me some relief from this tilted-crosshair syndrome. I use the DeadEye Precision Scope Leveler, Stoney Point gadget and the Reticle Leveler with the little lines on it that attaches with elastic bands and they work but believe it or not I sometimes scew them up and get the crosshairs sloped. Takes a really screwed up eye to booger things with those tools, but I can do it. Anyhow, Ward at Sniper Tools has fixed my problem. His new tool works for me, I am happy, slept better last night, the world is brighter and a happier place for me at least. Bottom line, this is not a gadget, it is the slickest idea and nobody saw the logic until Ward brought us his C-Level. I am not in Ward's pocket. I am not promoting this for him. I am not making any money from this. I just want you guys to know that the C-Level procedure is easy and accurate. Some guys might mount a scope perfectly every time, I cannot come close. Now with the C-Level I am confident the scope is mounted perfectly. How does it work? About simple as I can handle. First my buddy and I stretched about six feet of masking tape on a wall at the range. We used a four foot level to keep the tape horizontal. Then I set my rifle back about 20 yards, it is sitting on a swivel Harris bipod. Then I roughly line the crosshairs with the tape. Then I put the C-Level under the scope, its magnets grab the picatinny rail and it sits nice and solid. Then I hunch down and line the C-Level with the big long tape and tighten the Harris. Then I pinch the rifle upwards on the sandbag at the toe of the butt and line the crosshairs up to the top of the tape. The scope is loose in the rings, I adjust the scope a bit to line the crosshairs as mentioned and then snug the screws so the scope cannot move. Then I torque the scews to 16 inch-pounds and all is done. Slick. Absolutely works. Damn, I felt good, knowing I did not scew-up another scope installation. No more ten degrees tilt. Merry Christmas. I have some images, maybe Ward could put them on the site if he has time.
