Overview
Built for .223/5.56 flattop rifles, this fixed 4x optic combines a chevron ranging reticle with bullet drop compensation calibrated out to 800 meters. The tip-zeroed chevron and silhouette ranging references make it well suited for hunters and shooters who want a simple aiming system for distance work and close-quarters use with both eyes open. Dual illumination uses tritium and fiber optic elements to adjust brightness automatically based on available light, so the reticle remains usable from daylight into low-light conditions without batteries. The package includes a TA51 flattop mount, scopecoat, Lenspen, logo sticker, and ACOG manual.

Considerations & Trade-offs
- The chevron reticle is set up around a 100-meter zero, so it is not a general-purpose holdover system without that setup.
- The ranging and bullet drop compensation are calibrated for 5.56mm (.223) flattop rifles, so the reticle is purpose-built rather than universal across calibers.
- The optic uses dual tritium/fiber optic illumination, which is battery-free but depends on available light for brightness adjustment.
- The package includes the TA51 mount and accessories, but the optic’s compact fixed-magnification format leaves less flexibility than variable-power scopes for changing distances.
