WheelerProfessional Laser Bore Sighter with Magnetic Connection, Multiple Caliber Usage and Storage Case for Scope Mounting, Gunsmithing and Maintenance

The Wheeler Pro Sight seems to be very accurate. I have tried other bore sights in the past which were caliber specific and never had much luck with results. This sight is easy to use and the result were better excellent. Very good quality product. I got the green laser. I felt the green had some advantages over the red especially when bore sighting red dot scopes or anything with a red reticle.Here is how I found as the best way to use the bore sight:I have an area in my house with a long hallway and was able to set up a small portable table with clear line of sight at 16 yards. In reality if you can get the target and rifle about 25 yards that would be more ideal, but 16 yards was the best I could do indoors.The first optic I mounted was a Sig red dot. With the red dot turned off, I held the rifle in my normal comfortable shooting position and moved the optic along the Pic-rail until the eye relief was in a comfortable position. This went on a .40 pistol carbine. The second optic mounted was an ACOG non led 3.5X scope. This was going on a 308 AR10 style rifle. After both optic were secure on the rifles then I began the bore sighting process. First I did the red dot optic.1) I placed the rifle in a cleaning rest ( any type of rest is good, the idea is to make the rifle stable so that you are free to use both hands). Make sure the rifle is totally unloaded and nothing in the chamber before proceeding.2) I put some blue painters tape over the magnet just to provide a protective barrier between the barrel and the magnet. Mounting the bore-sight I found was easier to approach at an angle and ease it on the barrel. The magnet is super strong and I did not want to let it snap attached to the barrel. After it is in place the idea is to center the hole of the barrel about dead center of the magnet. Then I turned on the green laser.3) The next step was to take the included reflective target and already having the rifle and green laser pointing at the wall, I used painters tape to attach the target to the wall so that the green laser was exactly on the bulls-eye.4) Next, I turned on the red dot and made windage (right-left) and elevation (up-down) adjustments until my red dot was lined up with the green laser. A trick that helped me was to turn the red dot up in brightness to where it was slightly brighter than the green dot. This allows almost an eclipse effect to be seen when you get the two dots lined up. I think this is also an advantage to having the green bore sight vs the red. At this point the bore sighting is complete.5) same process with the ACOG except you line up the reticle ad center to the green laser.Range results: (indoor range):This was a .40 pistol carbine and was a new rifle. I put the target at 25 yards and fired two shots (bench rested). The groups were within 1/2 inch so I was pleased with the grouping. POI on both shots were about 4 inches high and about 3 inches left of where I had the red-dot. This was very impressive to me to be more than just on paper at 25 yards. A few shots and adjustments later and I was ready to move out to 50 yards and complete the sighting in process. Non- Magnified red dots I only sight in to 50 yards especially with this just being a pistol carbine.Next up was the 308. This was a rifle that I already knew held very tight sub moa groups so I just lined it up and fired one shot but tried it at 50 yards and I was amazed to be on paper at 50 yards with the first shot. The shot was about 7 inches low and about 5 inches right but for bore sighting I was really impressed with how close this Wheeler pro got me. After some adjustments I was ready to move to 100yrds and completed the sight in process.Over all I am very impressed with this bore-sight. It is truly a multi-caliber bore sight and much more accurate than caliber specific sights that I used in the past which required plugs inserted into the barrel.Pros:Quality builtStrong laser (green)accurateEasy to useCons:Price higher than others but more accurate and well builtWish the laser brightness could be dimmed when using indoors but this is a picky complaint.

This is the BEST bore sighting tool on the market. Works awesome and very low priced. My local FFL had one and told me about it. So I had to get one. It has been used to sight in several rifles. It is very easy to use and reduces the time required to sight a rifle in, and it saves you lots of ammo and time! I love it.

I bought this bore sighting tool because the owner of the local gun store recommended it. It’s been a great purchase and has made it very easy to sight in my new optics. It’s well made. The laser is strong and easy to see, even in daylight. The magnetic attachment makes it quick and easy to use. It’s allowed me to sight in guns in just a few minutes. I’ve found it to be very accurate, so I have great comfort with anything I’ve sighted in with it. If you’re a gun owner, this is a must-have tool.

Easy to use and works great, although trying to center it properly is admittedly a pain. Has helped me bore sight in many optics.

I do not know how or why, but this device truly works. I have used it on iron sights, lasers, and scopes. All of them were in the black at 50 yards. I adjusted and moved out to 100 yards for the final adjustments. It should pay for itself in saved ammunition. It is highly magnetic, so you need to attach it to something magnetic, such as directly to your barrel.
