Frequently Asked Questions
Will the HiViz H3 CompSight fit my shotgun?
The HiViz LightWave H3 (PMN301) is designed to fit most vent-ribbed shotguns that have a removable front bead. This covers a wide range of popular hunting and sporting shotguns from brands like Mossberg, Remington, Browning, and Beretta, among others. If your shotgun's front bead is threaded and removable, this sight should be compatible. When in doubt, check the thread size of your existing bead against HiViz's fitment guide or contact HiViz directly.
How does the H3 tritium element work, and how long will it last?
The H3 in the name refers to tritium, a naturally radioactive isotope of hydrogen that emits a steady, low-level glow without requiring any batteries or external light source. This means your sight will be visible in complete darkness. Tritium has a half-life of approximately 12 years, so your sight will provide reliable low-light performance for well over a decade before the glow begins to noticeably dim. The fiber optic element works alongside it during daylight hours, collecting ambient light to produce a bright, crisp aiming point.
Can I install this sight myself, or do I need a gunsmith?
In most cases, installation is a straightforward DIY process. The HiViz H3 CompSight replaces your shotgun's existing threaded front bead — simply unscrew the old bead and thread in the new sight. HiViz includes the necessary hardware and instructions. A dab of thread-locking compound is recommended to keep the sight secure under recoil. No specialized tools or gunsmithing experience is typically required, making this an easy and cost-effective upgrade.
