[QUOTE="Broz, post: 763047, member: 7503"] I have installed a few PST's and lets be safe and count on 70 usable MOA of total elevation. In a perfect world, with spot on machining of both the rail and receiver top, with a zero cant rail you would have 35 moa up. With a 10 moa canted rail 45 moa up, 20 moa rail 55 moa up. 30 moa rail 65 moa up. If you push the limit of 1/2 your scopes total elevation (35) you could acquire a problem with 100 yards zero or being to close to bottomed out. So I feel you will be best served with a 20 moa rail. This will allow easy 100 yards zero, a good distance from bottoming the scope out at zero, and you should have 55 moa of dial up for long shots. Please understand that if you purchase a low end rail mount for $30 or $40 none of this is a given as you not end up with the desired moa of cant you ordered. I have seen it over and over. I good scope mounting system is not a place to skimp. Jeff [/QUOTE]
