Kahles Ballistic Drop Compensation HELIA 3

DESCRIPTION

The Kahles HELIA 3 ballistic curve compensation system, also called Ballistic Drop Compensation (BDC), is a system that enables very precise shots at any distance. Adjustment using the Kahles click is simple and precise. This BDC system is housed in a metal housing that closes with a magnet to prevent accidental adjustment and protect it from the elements. This housing has an opening through which the shooter can see the adjustment while shooting.
