# CompM5b™

## CompM5b

The CompM5b turrets have been tested with different ammunition from FN, Nammo, Lapua/Norma, etc (All NATO Spec) using different bullet weights. Compensation is required in some instances depending on load. They may not be exact, but are close enough to engage targets quickly at distance. The Norma Ballistic App works extremely well for determining which turret works with your ammunition and will help set up the custom turret as well. Below are what each turret is specified for:  
Turret A - 5.56 cal, 14.5” barrel, 62gr bullet, 100 meter zero  
Turret B - 5.56 cal, 14.5” barrel, 62gr bullet, 200 meter zero  
Turret C - 7.62 cal, 16” barrel, 143gr bullet, 100 meter zero  
Turret D - 7.62 cal, 16” barrel, 143gr bullet, 200 meter zero
