An iconic magnified optic that’s still one of our favorites. Rugged, reliable, and one of the best in its class – the Trijicon ACOG 4×32 is as relevant as ever.

This is the TA02 LED, a 4×32 fixed power optic designed for .223 rifles. It features an illuminated reticle (chevron or crosshair) powered by a single AA battery. When turned off, you can still see the dark, non-illuminated etched reticle in the glass. The glass is super clear, the reticle is easy to use with six brightness settings, and the overall construction of it solidifies it as one of the most durable optics in the market. This optic also comes with a Picatinny mount and top screws which allow for the installation of an additional optic plate (ideally for a 1x dot like the RMR). The scope can easily be used to hit targets at 500+ yards.

Which reticle type should I go with? Crosshair or chevron?
The answer to this one really just comes down to your personal preference. If you’re already used to one, go with that one. There’s no inherent superiority of one over the other.
