I'm experiencing sighting and accuracy issues (e.g., sights shooting lower than the point of aim).
This variance is normal and is due to mechanical offset. Because your optic sits higher on the chassis upper rail than it does on a standard pistol slide, your point of impact will naturally print lower than your chosen point of aim at closer ranges.
You will need to manually re-zero your optic for your preferred target distance while it is mounted on the chassis system.
🎯 Backup Iron Sights (BUIS) Check: It is also possible your BUIS (Backup Iron Sights) do not have the required elevation adjustment built into the front post structure. You may have to modify your current sights or purchase validated sights directly from our store that we have tested and certified.
