Bushnell Professional Boresighter with Arbor Kit: A Comprehensive Review

The Bushnell Professional Boresighter with Arbor Kit is a highly regarded tool among shooting enthusiasts and professionals alike. This device is designed to assist in the precise alignment of rifle scopes, ensuring that your shots are on target right from the start. In this article, we will explore its features, benefits, and overall effectiveness.

Overview of the Product

The Bushnell Professional Boresighter is a collimator-type bore sighter that allows shooters to align their scopes without firing a shot. It comes equipped with three expandable arbors that fit various calibers ranging from .22 to .45, along with a fixed arbor for .17 caliber rifles. This versatility makes it suitable for a wide range of firearms, including rifles and shotguns.

What’s Included in the Kit?

When you purchase the Bushnell Professional Boresighter, you receive:

• The main boresighting unit
• Three adjustable arbors (.22-.27, 7mm-.35, .35-.45)
• One fixed .177 caliber arbor
• A felt-lined leather protective case
• Detailed instructions for use

This comprehensive kit ensures that users have everything they need to get started with bore sighting.

How It Works

Using the Bushnell Professional Boresighter is straightforward. The device replicates a distant target by creating an optical grid that aligns with the rifle’s bore axis. Here’s how to use it effectively:

1. Insert the Arbor: Select the appropriate arbor for your rifle caliber and insert it into the barrel.
2. Align the Scope: Look through your scope while adjusting its windage and elevation settings until the reticle aligns with the grid displayed by the boresighter.
3. Fine-Tuning: After aligning at close range (typically around 25 yards), take your rifle to a longer distance (100 yards) to make final adjustments based on actual shooting results.

This method allows shooters to achieve a rough zero before heading to the range, significantly reducing ammunition waste during initial sighting.

Advantages of Using the Bushnell Professional Boresighter

Cost-Efficiency

One of the primary benefits of using this boresighter is its potential cost savings. By allowing shooters to accurately align their scopes at home or before heading out, it minimizes wasted ammunition during zeroing sessions. Given current ammunition prices, this can lead to significant savings over time.

Diagnostic Capabilities

Unlike laser bore sighters that only provide alignment assistance, collimator-style devices like this one can also help diagnose scope issues. Shooters can verify if their scope tracks properly by observing how much adjustment occurs when they dial in changes. This feature adds an extra layer of utility beyond simple bore sighting.

Ease of Use

The Bushnell Professional Boresighter is designed for ease of use. Its lightweight construction and compact size make it easy to handle and transport. Additionally, users report that once familiarized with its operation, they can achieve consistent results quickly.
