Capture the action with precision and passion using our Sub MOA Checker Combo. Designed for competition shooters, this quick guide lets you see if you have an accurate group at the range—just hold it up to your group, and if all shots are within it, you've achieved a sub-MOA group! As a bonus, it comes with a free checker for your buddy. At Top Gun Mounts, we are dedicated to providing shooters with top-notch, reliable tools to enhance their accuracy and performance.
