Trijicon ACOG 4×32 Riflescope – Crosshair 300 BLK BDC
The Trijicon ACOG 4×32 BAC Riflescope with 300 BLK BDC Crosshair Reticle (TA31-C-100413 & TA31-C-100411) is a fixed-power optic designed specifically around the ballistic characteristics of the .300 Blackout cartridge. Its dual-illuminated green reticle combines fiber optics and tritium to automatically adjust to available ambient light without batteries. The specialized 300 BLK BDC reticle merges aiming points for both supersonic and subsonic ammunition, allowing shooters to transition between loads without re-zeroing the optic.
The 300 Blackout BDC incorporates 2 MOA diamond aiming points with supersonic holds extending to 600 yards and subsonic holds extending to 200 yards. The BDC is based on commonly available ammunition fired from a 16-inch barrel, providing a versatile reference for a wide range of .300 Blackout loads. The Bindon Aiming Concept (BAC) also supports both-eyes-open shooting for improved situational awareness and rapid target acquisition.
Rugged 4×32 ACOG Construction
Built with a forged aluminum housing and fixed 4x magnification, the Trijicon ACOG 4×32 minimizes moving parts while providing a durable platform for demanding applications. Fully multi-coated lenses deliver a clear field of view, while the nitrogen-filled housing helps prevent internal fogging. The optic is designed to withstand recoil from .22 LR through .50 BMG and exceeds military waterproofing standards.
With 4x magnification, a 32mm objective, 36.8 feet of field of view at 100 yards, and 1.5 inches of eye relief, the ACOG provides a practical balance of magnification and situational awareness. The package includes a TA51 thumbscrew flattop adapter, Scopecoat, and LensPen.
