The Trijicon ACOG USMC Rifle Combat Optic is a 4×32 riflescope for the M4 and M4A1 with a 14.5 in. barrel. It combines fiber optics and self-luminous tritium so the aiming point works without batteries. It has a red chevron reticle and a TA51 flat-top mount.
Features
- Dual illumination: Fiber optics adjust to daylight, and tritium lights the aiming point in total darkness.
- Bullet drop compensator: BDC for engagement out to 800 meters.
- External adjusters: External windage and elevation adjusters, so no tools are needed.
