Hi all, new to the forum and relatively new to 10 meter competitions. First off, I absolutely love my S400! I'm a big guy and would like to know if anyone has any info on sight risers for this rifle? Reason I ask is, about midway through a 60 shot course I am getting fatigued and can feel myself scrunching up to get the sight picture right. Always have problems getting a consistent cheek weld and sight picture but have been able to shoot well enough so far. Now changes are needed to get the next level. I already have the buttstock adjusted all the way in order to raise the butt up on my shoulder but still need something extra. Any input from you folks with far more experience than I would be greatly welcomed! Thanks, Neil.
