Product Description The Trijicon ACOG 4x32mm Dual Illuminated Scope with Green Crosshair 300 Blackout Reticle (Model TA31-C-100413) is a combat-proven, battery-free optic engineered for shooters who demand absolute reliability in any light condition. Built around a tritium/fiber optic dual-illumination system, the reticle automatically adjusts brightness based on ambient light, eliminating the need for batteries entirely. The forged 7075-T6 aircraft-grade aluminum-alloy housing delivers a near-indestructible sighting platform that is waterproof, shockproof, and fogproof. Optimized specifically for the .300 Blackout caliber, the integrated Bullet Drop Compensating (BDC) reticle merges both supersonic (out to 600 yds) and subsonic (out to 200 yds) aiming points, allowing instant ammunition transitions without re-zeroing. Designed around Trijicon&';s Bindon Aiming Concept (BAC), this ACOG can also function as a Close Quarters Battle (CQB) sight with both eyes open. Made in the USA, it comes complete with a TA51 flattop mount and accessories for immediate deployment.
