NCStar Laser Boresight Kit Product Review

If you're anything like me, you are tired of all the cheaply made products in the
marketplace these days. I really want a well made product, and I am willing to pay more
initially if it truly is a good value. There is something about sturdy construction, multiple
uses, and adjustable options that leaves me with the impression that a product was
really thought through. This is definitely the case with the NcSTAR TLZ Laser
Boresighter Set.

When you receive the NcSTAR TLZ Laser Boresighter, the package includes the
• One laser unit
• One carrying case
• Instruction sheet
• Five metal arbors (from .15 to .55)
• Three batteries
• Two hex keys
• One slotted head screwdriver
• One "Special Adapter"



The first thing I immediately noticed and appreciated when I received the kit was the sturdy plastic case. The product was packaged securely. Compared to some other products available that give you a little bag that could be easily lost, this will not get lost or misplaced, and it is not so large as to be cumbersome. The carrying case is a really

The whole point of this product is to reduce the number of rounds you need to fire to properly sight-in a weapon. The instructions are straight forward and easy to understand. The product works exactly as described, with one exception. The laser is supposedly calibrated to the arbors that run from .15 to .35 caliber. If this unit came calibrated, it was done poorly. However, unlike other units where the laser is not adjustable, this one is fully adjustable. So it is really just a matter of sitting down and calibrating the laser before sighting in your weapon.

We will walk through the instructions here quickly so you can see how it works. I am going to skip checking your rifle to make sure it is ready to sight. So before you start this, please make sure your weapon is ready for sighting in. Also, as always, make sure your weapon is not loaded and you follow all basic firearm safety rules!

Using the product is fairly simple.
• First: Ready the firearm in a vice, and set up your work area including a target (a blank piece of paper will work).
• Second: Install the batteries. You do this by separating the two parts of the laser body. Unscrew the threaded end from the laser end. Install the batteries and then put it back together (notice the separation in the housing on the right). This might be very nit-picky on my part, but there is a clear plastic sleeve in the battery cavity that needs to be removed before you try to install the batteries. It is very easy to miss, and there was no mention of it in the instructions. There is a switch on the threaded end that allows you to turn the laser on and off (note the push switch on the right side).


• Third: To pick the appropriate arbor for your weapon, you find the largest arbor that will fit inside the barrel. Insert the arbor into the barrel, narrow end first. After the arbor is installed, you take the screwdriver included in the kit, and fit the arbor to the barrel by turning the screw head located inside the arbor. It will look like this:


• Fourth: Once the arbor is snugly fit in the barrel, you install the laser unit to the end of the arbor. It will now look like this:


• Once you turn the laser on you will need to either rotate the laser/arbor assembly in the barrel a quarter turn, or remove the assembly, and reinstall advanced either direction a quarter turn. If the laser moves on your target at all, you need to calibrate it.</p>

Like I mentioned earlier, I found that my unit was not calibrated well. In fact, at a mere five yards, it wasn't even on an eight and half by eleven sheet of paper after the first rotation! To calibrate the laser, there are four adjustment screws on the front of the laser (notice the hex screws on the left):


To calibrate the laser you need to have it installed in a weapon. To see which direction the laser is off center, you need to rotate the assembly in the barrel, or remove and then reinsert a quarter turn in either direction. Adjustment is achieved by loosening and tightening the four hex keys on the laser end. It is a somewhat time consuming process to calibrate exactly, especially seeing as it is a loosen/tighten, then rotate the laser/arbor assembly and see if the laser moves process. If you are patient, I imagine you could calibrate it to dead on, especially at closer ranges. The other option is to follow the alternate instructions also listed in the literature, which is to set your scope for the center of the "laser circle". That is not a bad idea, but it could use a little elaboration. So if like me, you get the laser calibrated to where it is making a circle on a

• Mark a target with the laser location. Then either pull the laser, rotate and reinstall; or just rotate the arbor/laser assembly and mark the next location. You will end up with a
target that looks like this:


• Once you have your circle/square marked on the paper, find the center of it. You now have your windage center, and depending on distance between you and the target, you can adjust your elevation appropriately.

The "Special Adapter" lets you mount this laser to the barrel of a rifle. This is great because it really makes this product a multi-use laser instead of just a boresighter. Mounted to a rifle this laser could be calibrated to mark point of impact at any distance desired given proper environmental conditions.

The thing that I really like about this product is the stout build. There is no plastic used to make the laser boresighter. The second thing that really sets this product apart is the adjustability. The fact that the laser can be calibrated is an awesome addition. Many of the competing products are not adjustable. If the laser is off the mark, tough luck. I also like the idea of the special adapter, it really adds to the versatility of this item.

The biggest concern I have with this item may be unfounded. I am a little concerned that rotating a metal arbor in a metal barrel may cause some scuffing or scratching. I don't know this for sure, but it is definitely a reason to fully calibrate the laser, at least in my mind. To address the issue that I found with the product, it would have nice had they designed around it. Maybe something as simple as a rubber or plastic coating on the end of the arbor that rotates in the barrel. I also imagine it would have been possible to design the arbor in such a way that the part in contact with the barrel didn't need to rotate, but still allow the laser end to rotate.

I definitely consider this a worthy tool. I believe it is well built, serves many purposes and would be a great addition to a basic gun maintenance kit, especially for those who work in multiple calibers and prefer heavier grade items.

Update- While evaluating the product further, and discussing it with other people. The point was raised that one could simply tighten the laser head all the way down, make a mark, loosen just the laser head one quarter turn, make a mark, and repeat twice. This would eliminate the need to rotate the entire boresighter in the barrel.
