Special Features

• The magnetic snap-on base attaches and removes without tools, allowing the shooter to mount or swap the sight in seconds without permanent modification to the shotgun rib
• HiViz LitePipes are interchangeable, so the shooter can switch between green, red, or the exclusive two-tone green with red center pipe to match lighting conditions or personal preference at any time
• The Two-Tone LitePipe is a HiViz exclusive design that combines a green outer bar with a red center dot, creating a high-contrast aiming reference that stands out in both bright and low light environments
• Two LitePipe diameters, 0.135 inch and 0.175 inch, give the shooter the option to run a tighter or broader light-gathering profile depending on their shooting style
• No drilling, tapping, or adhesives are required, making this a fully reversible upgrade that leaves the factory rib untouched

Practical Benefits

• Hunters and sporting clay shooters running a narrow-rib shotgun can drop this sight onto the rib before a round and remove it afterward without affecting the factory configuration
• The bright fiber optic pipe pulls ambient light into the sight picture, giving you a visible aiming reference in shaded woodland settings, overcast skies, and indoor range lighting
• Waterfowl and upland hunters who switch between multiple shotguns can move this sight from gun to gun without buying a separate dedicated sight for each rifle
• The included selection of three LitePipes lets you dial in the color and size that your eye picks up fastest, which improves your mount-to-shot speed in the field or on a competitive course
• You get a permanent-free fiber optic upgrade for your shotgun that installs in seconds and gives your eye a bright, consistent reference point every time you mount the gun

The HiViz M300 M-Series Magnetic Front Sight (M300) is a smart addition for narrow-rib shotgun owners who want faster target acquisition and the flexibility to customize their sight picture without committing to a permanent modification.
