The Swampfox Warhorse 1-6x24 LPVO, produced by Swampfox Optics, is a low-power variable optic designed specifically for modern sporting rifles like the AR-15 rifle platform.
The Hi-Lux TD-3C Red Dot Sight, produced by Hi-Lux Optics, is an affordable pistol red-dot optic designed for shooters who want reliable performance without paying premium prices.
With an MSRP of $219, the TD-3C offers many of the features typically found in more expensive pistol dots. Reviewer Jack Oller describes it as a surprisingly capable optic that performs well beyond its price category.
Hi-Lux has a reputation among firearms enthusiasts for producing both modern optics and replicas of historical military scopes, including early Malcolm scopes and Vietnam-era sniper optics. The TD-3C represents the company’s modern approach to pistol red dots.
The TD-3C uses a 7075-series aluminum housing, the same type of material commonly used in high-end firearm optics.
Key design features include:
Because it uses the Trijicon RMR footprint, the TD-3C can mount easily to many optics-ready pistols or adapter plates.
The optic also includes a Picatinny rail adapter, allowing it to be mounted on rifles or shotguns as well.
One standout feature of the TD-3C is its impressive battery life.
The optic runs on a CR2032 battery that installs from the side of the optic, meaning the sight does not need to be removed from the firearm for battery changes.
Battery performance includes:
These features help extend battery life while preventing accidental battery drain if the sight is left on.
Unlike many pistol red dots that use a square or circular window, the TD-3C features an oval-shaped objective lens.
Although it may appear smaller at first glance, the design actually provides a comfortable and usable field of view.
The shape helps shooters quickly locate the dot when presenting the pistol and makes target transitions smoother during rapid shooting drills.
The TD-3C includes two reticle choices that can be toggled by the user:
Many shooters prefer a simple dot for precision, but the circle-dot configuration can make target acquisition faster in close-range defensive scenarios.
Brightness controls are located on the left side of the optic and provide tactile feedback when pressed.
During testing, the TD-3C was mounted on a Shadow Systems DR920 pistol, where its compact design kept the optic mounted low on the slide.
The optic performed well during:
Testing also took place at Gunsite Academy, where the optic handled bright sunlight conditions without issues.
The reviewer also noted that the optic would work well on shotguns, particularly for turkey hunting, thanks to its included Picatinny mount.
One concern shooters often have with red dots is durability, especially when mounted on shotguns.
However, optics designed for pistols already endure extreme forces from the slide movement of semi-automatic handguns. In fact, the slide movement of a compact pistol can produce forces approaching 9,000 Gs, which is often harsher than shotgun recoil.
Additional durability features include:
This makes the TD-3C suitable for range use, home defense, and hunting environments.
Visibility is one of the most important aspects of a red-dot sight.
During testing in the Arizona midday sun, the TD-3C’s dot remained:
The two lowest brightness levels are also intended to be night-vision compatible, though that feature was not tested in the review.
Manufacturer: Hi-Lux Optics
The Hi-Lux TD-3C Red Dot Sight offers an impressive combination of affordability, durability, and practical features.
While it lacks some advanced features found on high-end optics—such as automatic brightness adjustment—it still delivers the essentials that matter most:
For shooters who want to try a pistol red dot without spending $400–$600, the TD-3C represents an excellent entry point. It’s suitable for training, home defense, hunting shotguns, and general range use while staying well within a modest budget.
