Trijicon ACOG, 4x32, Dual Illuminated Green Chevron, ARMY Rifle Combat Optic (RCO) for the M150, With TA51 Mount TA31RCO-M150CP-G

The Trijicon ACOG (Advanced Combat Optical Gunsight) is a fixed power, compact riflescope with an illuminated reticle pattern for use in bright to low/no light. The ACOG is designed to be extremely durable and reliable. Combining traditional, precise distance marksmanship with CQB speed, many variants include a bullet drop compensated (BDC) reticle. Every feature of its design was chosen for a single purpose: to provide increased hit potential in all lighting conditions.
