HIVIZ Fiber Optic Rear Sight for S&W K/L/N Frame Revolver - Adjustable, Green/Red/White

A quality rear sight upgrade for your S&W revolver should be visible in all light conditions—and the Hi-Viz fiber optic rear sight delivers exactly that. Built to fit K, L, and N frame Smith & Wesson revolvers with factory adjustable rear sights made from 1998 onward, this adjustable rear sight replaces your factory unit with a bright, easy-to-acquire sight picture. The fiber optic design gathers available light and presents a vivid aiming point, cutting through low-light scenarios where conventional sights fade. Whether you're running your carry revolver at the range, practicing defensive drills, or working through your duty gun, a visible rear sight matters when speed counts.

Hi-Viz includes both green and red LitePipes with this sight, so you can match your lighting preference or swap them based on your shooting environment. The adjustable design means you can dial in your zero without fumbling with aftermarket tools or gunsmithing—a practical touch for shooters who want a true drop-in upgrade. The sight maintains the adjustability you're used to, so your existing revolver workflow doesn't change; only your sight picture improves.

Revolver shooters often overlook sights because factory units come standard, but upgrading to a fiber optic rear sight is one of the easiest performance gains you can make. If you're serious about revolver accuracy, faster target acquisition in varying light, or simply want sights you can actually see clearly when it matters, this is a straightforward, proven upgrade.

Frequently Asked Questions

Will this rear sight fit my Smith & Wesson revolver?

Yes, if you have a K, L, or N frame S&W revolver with a factory adjustable rear sight manufactured in 1998 or later. The sight is designed as a direct replacement for your existing adjustable rear sight.

What's the difference between the green and red LitePipes?

Both are fiber optic light-gathering pipes; the choice is personal preference and lighting environment. Green and red fibers perform differently under various light conditions, so Hi-Viz includes both so you can use whichever works best for your eyes and your range or carry situation.

Do I need a gunsmith to install this sight?

No. It's designed as a drop-in replacement for your factory adjustable rear sight, so installation is a straightforward swap. Your revolver's adjustment mechanism remains intact.

Can I adjust the zero after installation?

Yes. The sight is fully adjustable, so you can dial in your zero just as you would with the factory sight it replaces.
