Comparison Short Insights

When picking the best 12 gauge bore sight, a few key differences popped out to me. The MidTen Red and EZshoot Red (in tin case) both boast robust brass construction, giving them a really solid, premium feel and ensuring excellent chamber fit. The EZshoot Red (aluminum body) offers a lighter build, which might be preferred by some for weight savings, though I personally lean towards brass for durability in bore sights.

For laser visibility, the MidTen Green Laser is the undisputed champion. If you’re often bore sighting in brighter outdoor conditions or just struggle to see red, the brighter green dot is a significant advantage, even if it means a shorter individual battery life.

The DARKFANG also includes extra batteries and is notable for its exceptionally small and precise laser dot, which could be a deciding factor for those obsessed with minute adjustments.

Range-wise, most red lasers hit the 15-100 yards mark, which is perfectly adequate for initial zeroing. The MidTen Green extends that to an impressive 30-300 yards, making it more versatile for longer-range applications or larger areas.

Your Questions About the Best 12 Gauge Bore Sight Answered

How accurate are 12 gauge laser bore sights?

12 gauge laser bore sights are designed for high initial accuracy, typically getting your point of aim “on paper” within your target range (usually 15-100 yards for red, up to 300 for green). While they won’t completely replace live-fire fine-tuning, they drastically reduce the number of shells needed to get a precise zero. Think of them as an excellent starting point, not a final solution.

Is a red or green laser bore sight better for 12 gauge shotguns?

The choice between a red and green laser bore sight largely depends on your specific needs and environment. Green lasers are generally perceived as brighter and more visible in daylight or well-lit conditions, and often have a longer effective range. This can be a huge advantage for outdoor shooting or if you have difficulty seeing red. Red lasers, however, are typically more energy-efficient, leading to longer battery life, and they are usually more affordable. For indoor or low-light use, red lasers are perfectly adequate.

Can a bore sight completely replace live-fire zeroing?

No, a 12 gauge bore sight cannot completely replace live-fire zeroing. Bore sights provide an excellent approximation and a crucial starting point for aligning your optics or iron sights. However, factors like barrel harmonics, bullet drop, and shooter technique (which don’t affect a static laser) mean that a final, precise zeroing always requires firing actual ammunition and making adjustments based on real-world impact points. It’s a tool to get you very close, saving you significant time and ammo.

How do I use a 12 gauge bore sight effectively?

To use a 12 gauge bore sight effectively, simply load it into the chamber of your unloaded shotgun like a regular shell (always ensure the firearm is unloaded and pointed in a safe direction). The laser will project a dot from the barrel. Then, adjust your scope or iron sights until their reticle or alignment points coincide with the laser dot on a target. It’s best to do this indoors or in a shaded area where the laser is clearly visible. Remove the bore sight before firing.

What’s the typical sighting range for these 12 gauge bore sights?

Most red laser 12 gauge bore sights have an effective sighting range of about 15 to 100 yards, which is ample for most shotgun applications. Green laser bore sights, due to their higher visibility, can often extend this range, sometimes up to 300 yards, making them suitable for longer distances or larger open areas. Always check the manufacturer’s specifications for the exact range.

Are there any specific maintenance tips for my 12 gauge bore sight?

Absolutely! To keep your best 12 gauge bore sight in top condition, always remove the batteries when storing it for extended periods to prevent leakage. Wipe down the bore sight with a clean, dry cloth after each use to remove any residue. Store it in its original case or a protective pouch to prevent scratches or damage to the laser emitter. Avoid dropping it, especially if it’s a brass model, as this could affect its internal alignment and accuracy.

Do all 12 gauge bore sights fit every 12 gauge chamber?

Generally, yes. 12 gauge bore sights are caliber-specific and designed to fit standard 12 gauge shotgun chambers. Their dimensions mimic a 12 gauge shotgun shell. However, manufacturing tolerances can sometimes vary slightly between different brands of shotguns or bore sights. If you encounter a very tight fit, gently insert it, but never force it. It’s always a good idea to ensure your bore sight is from a reputable manufacturer to minimize any fit issues.
