All About the SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass: Start Here

As a gear and equipment specialist with over a decade of experience across diverse environments, I’ve learned to appreciate tools that streamline processes and eliminate guesswork. My workshop, lab, and field experiences have consistently pointed to one simple truth: precision matters, especially when you’re preparing for critical tasks. This led me to seek out a reliable method for quickly and accurately sighting in firearms, a process that can otherwise consume significant time, ammunition, and patience. My search for an efficient solution for my 20-gauge shotgun led me to the SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass. This compact device promised to take the frustration out of the initial sight-in process.

The need for such a tool became apparent after a recent frustrating range session where I was struggling to get my new optic dialed in on my 20-gauge. Each adjustment felt like a shot in the dark, eating into my available range time and my ammo supply. I considered a traditional bore snake with a sighting attachment, but the laser-based approach offered a more immediate and visual confirmation. My first impression of this SME bore sighter was its solid construction. The all brass housing felt substantial and well-machined, a welcome change from some of the flimsy plastic alternatives I’d encountered. It immediately conveyed a sense of durability and a commitment to quality materials. This unit offered a straightforward solution to a common problem, and I felt a sense of quiet satisfaction knowing I had a tool designed for this specific purpose.

Real-World Testing: Putting SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass to the Test

First Use Experience

I tested this bore sighter primarily at my local indoor shooting range, a controlled environment where I could meticulously observe its performance. My goal was to establish a baseline for my shotgun’s optic without wasting excessive ammunition. The initial setup was remarkably straightforward; I simply inserted the 20 Gauge Brass cartridge into the chamber, much like I would any other shotshell. With the action open, I pressed the activation button, and a bright green laser dot immediately projected forward, aligning perfectly with the bore.

The performance in this controlled environment was excellent. The green laser beam was clearly visible against the backstop, even with the ambient range lighting. There was no discernible flicker or inconsistency, offering a stable point of reference. The ease of use was a significant factor here; it was intuitive from the start, requiring no complex instructions or calibration. My only minor surprise was how solid and secure the brass cartridge felt when seated in the chamber, a testament to its precise manufacturing.

Extended Use & Reliability

After several range trips and a few dozen uses for sighting in different 20-gauge shotguns, this bore sighter continues to perform admirably. It has become an indispensable part of my pre-shoot routine, consistently allowing me to get on paper within a few shots. The durability of the brass housing has proven itself; I’ve accidentally dropped it on the concrete floor of my workshop more than once without any ill effects.

There are no signs of wear and tear, such as cracks, stiffness in the activation button, or diminished laser output. Maintenance is virtually non-existent; a quick wipe-down with a soft cloth after use is all that’s needed. Compared to other bore sighting methods I’ve employed, this unit significantly reduces the time and ammo needed for initial zeroing. It performs consistently, exceeding my expectations for a tool in its price range.

Breaking Down the Features of SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass

Specifications

The SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass is designed specifically for 20-gauge firearms. Its all brass housing provides a robust and durable construction, ensuring it can withstand the rigors of regular use in various environments. This particular model utilizes three alkaline batteries to power the green laser beam.

The choice of brass is not merely aesthetic; it contributes to the weight and feel of the unit, making it easy to handle and seat properly in the chamber. The green laser color is generally more visible in daylight than red lasers, which is a significant advantage when sighting in outdoors. The unit is supplied as a single piece, ready for immediate use straight out of the packaging.

Performance & Functionality

The primary function of the SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass is to provide an accurate point of reference for aligning firearm sights or optics. It performs this task exceptionally well. By projecting a laser dot that is collinear with the bore, it allows the user to make initial sight adjustments quickly and efficiently.

The main strength of this bore sighter is its convenience and accuracy in establishing a close-to-zero sighting. It takes the guesswork out of that crucial first step. A minor weakness, inherent to all laser bore sighters, is that the dot size can become larger at greater distances, potentially introducing a small margin of error for extremely precise adjustments. However, for establishing an initial sight-in, it performs admirably and meets its intended purpose without issue.

Design & Ergonomics

The design of this laser bore sighter is fundamentally practical and effective. The all brass housing is not only durable but also provides a satisfying heft that feels substantial when handling. Its shape mimics a standard 20-gauge shotshell, allowing for easy insertion into the firearm’s chamber.

Ergonomically, it’s simple: a small button on the side activates the laser. This design is intuitive and requires no learning curve. The smooth, polished brass surface feels good in the hand, and the overall finish suggests good manufacturing quality. There are no extraneous parts or complicated controls, which contributes to its ease of use.

Durability & Maintenance

Given its all brass housing, the durability of this unit is excellent. It’s built to last and withstand the typical knocks and bumps associated with firearm accessories. I have experienced no issues with cracks, deformation, or loss of structural integrity, even after accidental drops.

Maintenance is straightforward; a simple wipe-down with a dry cloth is sufficient to keep it clean. Ensuring the battery contacts are clean and free of corrosion will help maintain consistent laser output. There are no specific points of failure to worry about, making it a low-maintenance tool. Its robust construction suggests it will remain a reliable companion for many years.

Accessories and Customization Options

The SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass is a standalone product, and as such, it does not come with any additional accessories. Its design is self-contained and focused on its primary function. There are no obvious customization options for this particular model.

However, the unit is designed to work with standard 20-gauge chambers. The simplicity of its design means it doesn’t require any external attachments or modifications to function. The included alkaline batteries are a standard size, readily available for replacement when needed.

Pros and Cons of SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass

Who Should Buy SME Sight-Rite Laser Bore Sighting System 20 Gauge Brass?

This bore sighter is an excellent tool for any owner of a 20-gauge shotgun who frequently scopes or re-scopes their firearms, or for those who want to ensure a quick and efficient sight-in process. It’s perfect for home range users, hunters, and sport shooters who value accuracy and efficiency. If you’ve ever experienced the frustration of wasting ammo just to get your sights close, this device will be a welcome addition to your gear.

Those who need extreme precision for extremely long-range shots might find the laser’s dot size at distance a limiting factor, and might prefer a mechanical bore-sighting method or simply proceed directly to live fire at closer distances. For general use and initial sighting, however, it’s hard to beat. A must-have complementary item would be a supply of spare alkaline batteries to ensure you’re never caught without power at the range.
