Ask anyone who owns an AR (or might be in the market for one) why the platform is so appealing — beyond their world-dominating looks — and it almost universally comes down to the customizability of the platform.
It’s rare to find an AR owner that doesn’t want some kind of optic on their rifle — and with self-defense applications in particular, a red dot or holo sight is a great choice. With these close quarters optics you can keep both eyes open — allowing you to get on target and stay situationally aware without losing your peripheral vision.
These optics are also, however, failure points. That’s where offsets come in.
