Product Info for Trijicon TA31DOC ACOG 4x32 BAC Illuminated Crosshair Rifle Scope w/ Red Dot Sight and TA51 Mount Rifle Scope
Trijicon TA31DOC 4x32 BAC ACOG Gun Sight offers Docter Optic mounted on top for close combat shooting. The Trijicon Rifle Scope features Dual Illumination (Fiber Optic provides daylight illumination and tritium illuminates reticle at night). The ranging reticle is calibrated for 5.56mm (.223 cal) flat-top rifles out to 600 meters. Trijicon TA31-DOC ACOG Gun Scope includes Trijicon Flat Top Adapter TA51. Trijicon TA31-DOC 4 x 32mm ACOG Advanced Combat Optical Gunsights hit fast in any light. Trijicon ACOG 4 x 32 Rifle Scopes are internally-adjustable, compact telescopic sights with tritium illuminated reticle patterns for use in low light or at night. Bindon Aiming Concept (BAC) models feature bright daytime reticles using fiber optics which collect ambient light. Trijicon 4x32 ACOGs combine traditional, precise distance marksmanship with close-in aiming speed. Although Trijicon ACOG 4 x 32 Rifle Scopes TA31 & DOC have many features which are very advantageous for military use, they were developed by Trijicon without government funding. Designed for use with the M16 family, every feature of its mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions - without failure-prone batteries.![]()
