Williams Gun Sight Marlin 336 Adjustable Peep Wgrs Receiver Rear Sight Black
Williams Gun Sight
The Williams Gun Sight adjustable rear sight for Browning Buckmark pistols brings genuine visibility upgrades to your handgun's factory setup. These tritium-powered sights gather ambient light to create a glowing 3-dot sight picture that works whether you're shooting in bright sunlight or dim indoor ranges. The front sight features a red insert while the rear carries two green inserts, giving you a clear, contrasting aiming reference that your eyes naturally center. If your Buckmark originally shipped with an adjustable rear sight, this replacement maintains that functionality—letting you dial in your point of aim instead of being stuck with a fixed setup.
Built as a direct replacement for factory Buckmark sights, the Williams installs without gunsmithing. The brightness of the tritium rods scales with available light; more ambient illumination means a brighter glow, so these sights perform equally well in mid-day matches and low-light practice sessions. The adjustable rear sight accommodates rear sight lengths over 1", making it compatible with standard Buckmark platforms. Whether you're running your pistol at the range or in practical shooting sports, these sights give you the repeatable sight picture and visibility that factory Buckmarks often lack.
Tritium sights don't require batteries or a flashlight to function, so they're as reliable as your pistol itself. You'll get the same no-nonsense, field-proven engineering that's made Williams a trusted name in handgun and rifle sights for generations. Drop them in, zero them on your dime, and forget about them until you need them to work—which they will, every time.

No, these are direct replacements designed to install on the Buckmark without additional gunsmithing.
No. Tritium sights are self-illuminating and require no batteries or external power source. They glow passively and appear brighter as ambient light increases.
The front sight has a red insert for your front post, while the rear sight has two green inserts. This red-and-green combination creates high contrast in your sight picture and helps your eyes naturally center the front sight between the rear dots.
