Who This Is For
This HiViz front sight is ideal for AR-15 and M4 owners who rely on iron sights and want a meaningful upgrade over a standard black post. Whether you're a competitive shooter chasing faster splits, a hunter who takes their rifle into the field, or a home-defense owner who needs a reliable sight picture in low light, the ability to switch between red and green LitePipes means you can optimize contrast against any target or background. It's an especially smart addition for shooters with aging eyes who struggle to pick up a plain front post quickly.

Frequently Asked Questions
Will this HiViz front sight fit my specific AR-15 or M4 setup?
This sight is designed to fit AR-15 and M4 rifles that use a standard A-frame front sight base, including both fixed (non-removable) and detachable (folding or flip-up) configurations. If your rifle uses a low-profile gas block without a raised front sight tower, this product is not compatible. When in doubt, check whether your current front sight post sits atop a triangular A-frame housing — if it does, this HiViz sight should be a direct fit.
How do the LitePipes work and can I swap them in the field?
HiViz LitePipes are fiber-optic rods that passively gather and concentrate ambient light, producing a bright, glowing aiming point without batteries or electronics. Swapping between the included red and green pipes is straightforward and can be done quickly without special tools, making it easy to switch colors based on target contrast, lighting conditions, or personal preference — even at the range between strings of fire.
Do I need a matching HiViz rear sight to use this front sight?
No — the HiViz AR-15 front sight is designed to work as a standalone upgrade alongside your existing rear sight, whether that's a standard A2 rear aperture, a flip-up BUIS, or an aftermarket iron sight. The illuminated front post naturally draws your eye and pairs well with any rear aperture. However, if you want a fully matched fiber-optic system for maximum speed and consistency, pairing it with a compatible HiViz rear sight is an excellent option.
