The HIVIZ Interchangeable Front Sight for Ruger Mark I-IV & 22/45 Pistols brings visibility and quick target acquisition to one of America's favorite .22 rimfire platforms. Whether you're shooting at the range, plinking, or training new shooters, a bright front sight makes a tangible difference—and this modular design lets you swap fiber-optic colors to match lighting conditions and personal preference without tools or gunsmithing.
This sight fits Ruger Mark I, II, III, and IV models with steel bull barrels, plus the Ruger 22/45 pistol (when paired with an adjustable rear sight—note it doesn't work with the LITE variant). It's also compatible with Ruger Single-Six revolvers that have an adjustable rear sight and Browning Buck Mark pistols, with the exception of the Challenge, 5.5 Target, and 5.5 Field models. That versatility means one purchase can serve multiple guns in your battery.
The package includes six interchangeable LitePipes in red, green, and white—two of each color. LitePipes are Hi-Viz's proprietary fiber-optic tubes that gather ambient light and glow without batteries. Swap them in seconds to dial in contrast under overcast skies, bright sunlight, or indoor range lighting. If a LitePipe gets damaged or you simply want to keep spares in your range bag, replacements are readily available from Hi-Viz.
This is practical gear for shooters who want better sight picture on a rimfire that's already simple and reliable. Installation requires no special tools, and the modular approach means you're not locked into one color or stuck if a fiber tube gets dinged.

No. This sight is designed for the standard Ruger 22/45 with an adjustable rear sight, but is not compatible with the 22/45 LITE model.
