If you are running a red dot setup and want better target identification without adding bulk, the FXD 4x in black is a practical upgrade. This compact magnifier by Aim-O is designed to integrate seamlessly with Picatinny platforms while maintaining a clean and efficient profile.

The body is CNC-machined aluminum with a non-reflective finish, helping reduce glare in dynamic environments. The flip-to-side mount with quick detach allows instant transition between 4x magnification and standard red dot view, without disrupting your setup.

Multi-coated scratch-resistant lenses provide clear and sharp vision, while the durable construction ensures long-term reliability even under heavy use.
