TLDR Review: "XS Sights Big Dot for Remington 870"
Pros
- •The large, bright yellow tritium dot is highly visible in loight and dark conditions, significantly enhancing target acquisition.
- •Installation is straightforward with numerous online resources and clear stey-step instructions available.
- •Does not rely on batteries, eliminating any worries about running out of power during critical use.
- •Provides a quick and natural aiming point that improves confidence for home defense or nighttime shooting.
- •The sight projects a soft glow and a distinct white "big dot" ring around the tritium vial, making it easier to pick up than standard factory bead sights.
- •Compatible and fits well on common shotguns like the Mossberg 500 and Remington 870 when properly measured.
- •Installation only requires basic prepping, adhesive cleanup, and standard tools, with JB Weld epoxy recommended for a secure mount.
- •The design looks clean and can appear factornstalled, adding an aesthetic upgrade along with functionality.
- •Significantly outperforms traditional bead sights and even some ghost ring sights in loight scenarios.
- •The gloing and bright green color options further enhance visibility across different lighting environments.
Cons
- •Installation is permanent and requires patience and precision; mistakes cannot be undone once epoxy sets.
- •Requires multiple tools and careful prep—abrading metal, cleaning with alcohol, securing the bead during drying—which may intimidate less handy users.
- •Does not perform as well in bright daylight or hunting scenarios compared to fiber optic sights, which remain more visible in full sun.
- •Using JB Weld or similar epoxy means some users may find cleanup and clamping cumbersome or timonsuming.
- •Less versatile for applications requiring quick changes or noermanent sight options.
- •Limited to certain shotgun models, so verifying compatibility before purchase is critical.
- •Not the best choice if you’re looking for an electronic red dot or LED sight with adjustable brightness and reticle options.
Bottom Line
The XS Sights Big Dot Shotgun Bead offers a no-nonsense, battery-free solution for shooters needing fast, reliable target acquisition in low-light conditions, especially for home defense or tactical use. Its bright tritium dot and glow ring make it far easier to pick up than traditional bead sights, but installation demands some DIY skill and care, with epoxy mounting being permanent. If you seek simple, rugged performance without fuss, this sight delivers well. However, if you want a sight optimized for daylight hunting or prefer non-permanent installation, fiber optic options might serve you better. Overall, this is a solid upgrade for Remington 870 and Mossberg shotguns that will boost your confidence in the dark.
