Boresight Comparison by Joel Zielke

In the last few weeks, I have had the opportunity to try out three different boresighters, in two different styles.  The first unit was a Bushnell Laser Boresighter, and the second unit was made by NcSTAR.  Both of these units are of the arbor type, meaning they actually attach the laser into the barrel of a firearm.  The third item I looked at was also manufactured by NcSTAR; however this unit is a cartridge style.  It is designed like a piece of brass (many different caliber options) but instead of a live round it has a laser installed.  What was interesting about these different offerings was that they all excelled in different areas.  It would be very difficult for me to point to one and say “You NEED this one...”.  Having said that, I hope I can help you select the most appropriate boresighter for your application.

Let’s take a quick overview of the three units.  My full reviews of these products can be found here on the website, so please take a look at those for more specific information regarding each unit.

The Bushnell Laser Boresighter

 

        

  1. One laser unit
  2. One carrying case
  3. Instruction set/small target
  4. Seven plastic arbors (from .22 to .50)
  5. Seven screws
  6. One hex key

The Bushnell Laser Boresighter is for the most price conscious purchaser.  It is a little more expensive than the cartridge style boresighters, but remember, a cartridge style boresighter only offers one caliber per unit.  This unit presents the most versatility for the cost.  The biggest upside to this unit after the price and versatility would how portable and compact it is.  This would be very easy to take to the range on your outing and not take up a ton of room in storage.  The biggest downside to this unit is the poor instructions.  I have outlined what I consider to be a superior method of using this tool in my review specific to this item. 

The NcSTAR TLZ Laser Borestyle

                     

  1. One laser unit
  2. One carrying case
  3. Instruction sheet
  4. Five metal arbors (from .15 to .55)
  5. Three batteries
  6. Two hex keys
  7. One slotted head screwdriver
  8. One “Special Adapter”

The NcSTAR TLZ Laser Boresighter is for a buyer seeking to maximize their value.  This unit is the most expensive unit I reviewed, however, it supports a wider range of calibers than the Bushnell Laser Boresighter, and is constructed from more durable materials.  The laser unit is adjustable, and the special adapter makes it suitable for on gun use as well.  The only issue I found with this unit would be inserting metal arbors into a barrel.  If done carefully I don’t see any real issues arising from it, but it is worth noting.
NcSTAR Cartridge Style Laser Boresighter

The NcSTAR Cartridge Style Laser Boresighter

  1. One laser boresighter in selected caliber (In this case, a 7MM Remington Magnum).
  2. Three batteries

The NcSTAR Cartridge Style Laser Boresighter is perfect for two types of buyers.  The first being someone who shoots a single common caliber, and the second being somebody who wants absolute ease of use above all. The greatest thing about this unit is it does not require any kind of calibration, and you don’t have to put anything into the barrel. This unit is the least expensive unit reviewed, however, it is by far the least versatile.  If you shoot multiple calibers you would need to have one of these for every caliber you shoot (assuming all the calibers you shoot are available).  Outside of the lack of versatility, and the fact that you are not supposed to chamber this with the bolt as some extractors can damage them, I don’t have any complaints.  In all seriousness, the lack of versatility is not really a valid complaint as it is the nature of the tool; it is only a negative when compared to the arbor style boresighters.

To summarize all the other more lengthy reviews, each of these tools have their strengths and weaknesses.  What it really boils down to is “What are you looking for?” and “What do you need?”.  These three types of boresighters will cover basically anyone who is looking for an easier way to sight in their weapons, but it is up to you to know what fits your needs.  Is price the bottom line?  Is getting maximum value of greatest concern?  Do you want ease of use?  One of these three will surely have you covered!
