Frequently Asked Questions
What firearms is the Trijicon ACOG RCO M150 compatible with?
The ACOG RCO M150 is designed specifically for AR-15, M16, and M4-pattern rifles chambered in 5.56mm NATO or .223 Remington. It ships with a flat-top Picatinny (M1913) mount for direct rail attachment. The BDC reticle is calibrated for 5.56mm ballistics, so it will perform optimally on rifles using that cartridge with standard-length barrels.
Does the Trijicon ACOG RCO require batteries to illuminate the reticle?
No — the ACOG RCO uses a self-powered dual-illumination system combining a fiber optic cable (for daytime brightness) and a tritium phosphor lamp (for low-light and nighttime use). This means the reticle is always illuminated and always ready, with no batteries to change or fail in the field. The tritium element has an approximate 15-year service life.
How does the M150 BDC reticle work, and how far does it reach?
The M150 red chevron reticle features bullet drop compensation hash marks calibrated for 5.56mm NATO ammunition fired from an M16-length barrel. The primary chevron is zeroed at 100 meters, with stadia lines extending the holdover system out to 800 meters. This allows trained shooters to engage targets at varying distances without manually adjusting elevation turrets, making it highly effective for both CQB and mid-range engagements.
