A customized elevation turret matches the shooter???s ammunition. The shooter determines range and dials in the exact yardage for precise aiming; there???s no need for holdover. A convenient WindMap feature helps you determine hold-off for your 5.56 or 7.62 cartridge. The C4 Wind MOA reticle has 1-MOA windage tick marks to help compensate for real-life field conditions. Solid one-piece tubes and internal double spring-tension assemblies are all designed for rough handling in the field.
