The closest competitor we have seen on the market is the Eotech style optics.  These seem to still gain a  lot of attention for house to house fightingi and close range shooting, but outside of 100yds, the Eotech reticle will most likely obscure a target.   If you’re picky about rifle recticles, you’ll have quite a few options to pick from with the ACOG.    Reticles come in red, yellow, amber and green.   They are crosshair, donut, Chevron or German style reticle.  There are a few optics that like the Accpoint that are even widely used in the hunting market.

Trijicon ACOG optics are hands down the most widely used combat optic used by our military.   There is a  reason for this.   These Trijicon ACOGS also known as Advanced Combat Optic Gunsights don’t need batteries, give you low light illumination, fixed magnification and models like the TRTA01-ECOS gives you fast up front CQB options and long range shooting in one package.  Like all optics being used today, nothing is good for everything, but technology is moving away from battery powered optics and Trijicon has been on that pursuit for over a decade.
