Professional Tactical Laser Boresighter Kit： Red or Green Bore Sight with 30 Adapters - Multiple Caliber Bore Sighting Laser - .17 Cal to 12GA Rifle Pistol Bore sighter - Perfectly Choice for All Gun

I had 9 guns I need sight in and I did not want to buy a separate laser for each caliber. I found this Professional Tactical Laser Boresighter Kit and read the reviews and it sounded like it was the one i was looking for. I used it on my .50 cal black powder rifle, multiple .556, a .308., a 12 guage bullpup, a .20g savage 220, and my 300 win mag. I did this in while sitting in my bedroom and sighting into my kitchen. I did all 7 weapons in less than 40 minutes. I went out to my sons farm and every single on was on the paper, I couldn't believe it. This boresight kit made my life so simple. I gave it five stars for accuracy, easy to use and the battery never gave out. Great product!

This Boresight was easy to use and great value for the money. I have a lot of target rifles and it has a barrel fitting for all of them including my 50BMG. It helps tremendously when I install a new scope or if one’s been sitting and I just need a zero. Honestly you can’t go wrong for the price. It all comes in a decent case so everything stays stable and doesn’t rattle around. I would definitely recommend.

Used this after I put a new scope on my buddies rifle. Worked really well for what seems to be just cheap plastic. After sighting in his scope, he told me it put him on paper at fifty yards. It is also fun to use. I have an expensive Bushsnell scope sighter and I like this one just as much.

Good product, would be five stars but the barrel spacers are a little difficult to figure out the sizing. You have to keep trying them till you get the right one. Just when you think you found it it’s not. But that’s just a small detail. Overall it’s a good product. Very bright laser to see down range.

Works great or I got lucky? Sighted in an IR scope with it, went to the range and was grouping tight and hitting AAA batteries at 100 yards. Haven’t adjusted the scope since initial bore sighting.

My husband loves it. It's everything he needed. Great price as well.

Quality item

(If I could give zero, I would.)This is hands down one of the worst firearm accessories I've ever purchased. A complete and utter waste of time, money, and patience. The quality is beyond cheap—flimsy plastic parts that don’t even fit properly inside the barrel due to random burrs and excess material. The so-called "bore adapters" are laughable at best, breaking after just a couple of uses. The items are not even straight. The screws? Useless. The laser? Completely inaccurate, unstable, and unreliable. It shifts with every adjustment, making it impossible to get a consistent zero!I tested this on multiple firearms, including a pistol that I knew was shooting low. The results? Even worse accuracy after "adjusting" with this overpriced toy. Whether it's a rifle or a handgun, this thing is a joke. It does nothing but waste your ammo and your sanity.To top it off, the return process is a scammy. I wasted my time trying to make this cheap piece of junk work. Bottom line: DO NOT trust this product. If you value your firearm, your wallet, steer clear.
