mini boresighter with switch

Layer bore sight works very well, with good features. There are 3 sizes of O Rings for different diameter barrels. I have used it on 9mm, .380 ACP and 22LR and 22WMR. I ordered the green laser which makes it much easier to zero a red dot optic with the differentiation in colors. Very responsive customer service for a question I had. Great price, great product and phenomenal customer service.

The only draw-back is the alignment O rings. They are very delicate, and I was too harsh with them. I ask to purchase more 'o' rings as I like the alignment tool very much. I was sent several packages from the seller with no charge. Thank you so very much! I used this to 'bore sight' to set up my at home assembled AR-15 W/20-inch barrel. (40-year earthmoving equipment mechanic but not a gunsmith at all) At the range first shot at100 yard was at 3:00 on the edge of the target. I was shooting 2" groups after the next 6 alignment shots. So quick and easy to get that scope Zeroed in! I will be using this on many of my other rifles and pistols to get a very close sight alignment for range zeroing in my scopes and my iron sights. Seller is very quick to respond to question and requests. GREAT people to work with. Just take care with the alignment O rings and you will enjoy long use of this tool. I will be buying other bore sized in the very near future.

I used the boresighter to sight a laser at home at 7 yards. At the range at 15 yards the boresighter said I was off quite a bit. So I re-adjusted. I was still off. With the boresighter in the barrel I rotated the boresighter. The dot traced a circle on the target. I removed the boresighter and gave it to my wife for her cat. Obviously the boresighter laser is not accurate. UPDATE: the vendor reached out to me and provided excellent customer service. The vendor response was 100% satisfactory and I am pleased with response. I am increasing my rating to 4-Stars because of vendor’s outreach.

I bought this boresight for my husband and he absolutely loves it! It’s of great value for the price, it is well designed, it is bright, and it comes with some “accessories”, including a tool that can be used to swap the rubber O-rings. To improve longevity, the O-rings should be lightly lubricated and the boresight body should be inserted in the barrel with a slight twist and preferably removed from the barrel in the same manner. Besides zeroing a sight on various firearms, this device can be used for other purposes, such as how to draw a handgun while avoiding muzzling others, etc. The manufacturer seems to have excellent customer service representatives (Candy comes to mind) and email inquiries are responded to quickly.

Works great. Nice fit to barrel.

Pin to base was bent thus accurate sighting in is impossible. Not worth the trouble to return etc. The iteme mechanical features i.e. laser worked but assembly was poor as described the 2 parts were loose and bent and useless to sight any weapon

Out of the box, this works decent for a 10/22 rifle, but I was unable to keep zero with the light. Anytime I removed it and put it back on, my zero would move. That's not accurate at all. Does it get me close to where zero might be? Yes and sighting in my iron sights worked decent to get it close to zero. I used my 10/22 for the initial zero because IT IS dead on. This led me to finding out that this tool is more of a cat toy. Save your time and get the ones with a longer barrel shaft for stability and accuracy. These with the shorter shaft have a lot of play. I gave 3 stars for a nice green light, pretty shell, and the attempt. Bottom line, look for one with a longer shaft for accuracy.

Took my 605 to the range before I ordered this. The pattern that was shot was dead on to the laser. This helped tremendously for me to adjust the sight. Thanks.
