Overview
The Trijicon ACOG 4x32 Scope in FDE is a fixed power prism scope that delivers 4X magnification, perfect for mid-range engagements. With an exit pupil diameter of 8.00 mm and an eye relief of 1.50 inches, it allows for a comfortable viewing experience, even in dynamic shooting situations. The reticle features a red BDC (Bullet Drop Compensator), providing precise aiming points for bullet drop at various distances, making it ideal for builders looking to enhance their accuracy. This scope is commonly found on builds with a mid-length gas system chambered in 5.56 NATO.
