its not perfect but it works. confirming your shot is important with these as generally advised with laser bore sights anyways. i sighted in a new rifle and had a successful hunt this year hit the animals right where i aimed so i would say its on

Solid product, easy to use, horrible batteries.
Overall a solid product, easy to use. Just unscrew the back, pop the batteries in and it's on and working. However, here is where I drop one star from my rating. I tested it at home and everything worked fine bright laser, fits in the bore of my rifle everything seems good. I had the batteries in the sight for less than 60 seconds to test it's functionality. Promptly removed the batteries and was excited to get to the range to sight in my rifle the next day. Next day I get to the range, setup the rifle, get the bore sight setup, and in the bore of my rifle. Before I could get my red dot turned on the batteries were dead in the bore site. I removed the site, and batteries, replaced them thinking I maybe put them in wrong, nope batteries were dead as a doornail. Wasted trip to the range as I didn't have spares with me. So do yourself a favor and buy extra LR41 batteries with this sight and save yourself a wasted trip to the range like I did.

Does the Job
I ordered this one because it is a combination. 308 and .243 bore sighter. I read some of the earlier reviews and have some thoughts about what was said and how this bore sight works. I used it in lower light. Not based on the reviews so much as I would have anyway, but it was bright in lower light and not too bright either. I noticed it was better to turn your scope down to a lower magnification if you have a variable power scope. If your scope isn't variable power it will still work, however the aim point won't be as precise. The batteries worked for me so that was not an issue. I unscrewed the cap and dropped them in. I bore sighted one rifle and confirmed zero on two others. When I was done I just took the batteries out and put everything back in the package. The lack of an on / off switch was not an issue for me. Though a professional may appreciate a switch. To each their own and everyone has different needs. I did notice the bore sight took a few times before it oriented properly in my barrel. I dropped it in the chamber and closed the bolt. After a few chamberings in my bolt action .308 I was confident the bore sight oriented properly. This was verified in my other .308 and my .243. 5 stars for the price. If this were a $50 item I would have given it 4 stars as I would have expected more. Your mileage may vary. But this bore sight got the job done.

Decent product but use in lower light conditions
I ordered this bore sighter along with one for my 5. 56 on the same day. I received them both together and found that the 308 did not work with the batteries they sent with it. The 5.56 did work so I tried those batteries in the 308 and it did work, leading me to the conclusion that the batteries that were sent with the 308 bore sighter were bad. I contacted the company and they sent me more details instructions on how to operate the the view sighters but that did not help so I notified them again about the continuing problem. They them all me off I could buy more batteries and I told them that I felt like it was their responsibility to send good batteries with the product since it did not work without the batteries. I told them that I would buy new batteries but, that it would reflect on my review of this product and that I would not buy from them again. THEN, they decided to do the right thing and send me more batteries or another bite sighter. I haven't received that yet so I am not sure what they sent. I would have been happier if they would have done the right thing and replaced the batteries right off the bat. I did try the bore sighter at around 3:00 PM on a sunny day and found that the bore sighter was useless in this much daylight. If you get one, use it in a little darker environment or you will not be able to see the laser. I am glad the company decided to make this right but, I wish they would have offered it first before I had to barter with them.

Works good
Works well in my AR10 but not in the 783. I honestly believe there is something wrong with my 783 as my son took it and tried it in his 700 and it worked great.
