Key Specifications – Trijicon 100432 ACOG 4x32 LED Green 300 BLK
Purpose-Built .300 BLK BDC Reticle – Supersonic & Subsonic in One Optic
The star of the Trijicon 100432 ACOG is its green .300 Blackout crosshair ballistic drop compensation (BDC) reticle. Instead of forcing you to choose one load profile, Trijicon merges supersonic and subsonic aiming points into a single, intuitive pattern: Palmetto State Armory+2EuroOptic+2
Supersonic BDC: Holds calibrated out to 600 yards.
Subsonic BDC: Holds calibrated out to 200 yards.
Merged aiming points: Let you instantly switch between sub and supersonic ammo without re-zeroing.
The drops are based on averages of commonly available factory .300 BLK loads, giving you a practical real-world BDC that works with typical hunting, defensive, and training ammo. Palmetto State Armory+2EuroOptic+2
For shooters who run both quiet subsonic rounds and full-power supersonic loads in the same rifle, this optic dramatically simplifies your sight picture.
LED-Powered Green Illumination – Control Your Brightness
