Trijicon TA31RCO Rifle Scope is an Advanced Combat Optical Gunsight (ACOG) designed for the weapon system (20" barrel). Trijicon TA31RCO- ACOG 4x32 USMC Rifle Combat Optic for the w/ TA51 Mount provides the shooter with quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to 800 meters utilizing the Bullet Drop . Trijicon TA31RCO-A4CP ACOG 4x32 Scope with BAC USMC Rifle Combat Optic (RCO) for incorporates dual-illumination technology using a combination of fiber optics and self-luminous tritium. This allows the aiming point to be always illuminated without the use of batteries.

This allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness. Trijicon TA31RCO A4CP 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. Trijicon 4x32 ACOGs combine traditional, precise distance marksmanship with close-in aiming speed. Although Trijicon ACOG 4 x 32 Rifle Scopes TA31RCO-A4CP have many features which are very advantageous for military use, they were developed by Trijicon without government funding. Designed for use with the 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.Trijicon TA31RCO-A4CP ACOG 4x32 USMC Rifle Combat Optical Sight for the w/ TA51 Mount Rifle Scope
