MidTen .243 308 Bore Sight Laser Red Dot Boresighters 308 with Batteries

It’s easy to use. The light was bright and accurate.

Works great. Would prefer to be able to turn it off without having to take the batteries out.

I picked this up for my AR10 308 win I just picked up and had to sight the rifle in over the past weekend. Easy enough to use the boresight as just insert the batteries and place the laser in the barrel. Outside the laser is too weak to be visible more than a few feet away so I initially went inside and got about a 50' span to line up my scope to the laser dot. Not much length but best I could do. I then went outside and took a shot at 50 yards. I was actually fairly impressed I got to around 8-10" of the target - I was expecting to be further off honestly for a $8 boresight laser. A few tweaks to the scope and was in business. It aint perfect but it gets you to the paper target to then fine tune your scope or iron sights for accuracy. I'd buy again.

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

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.

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.

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.

Not bright enough to use beyond 50 yards on a sunny day. It will get you on paper at 50 yards or less. At 100 yards it works if targets are in a shady spot but in direct sunlight you will see or find where the dot is located. I used the green dot also and it’s a way brighter but it will have same problem at 100 yards if it to bright outside. Indoor range they both work good if it not to bright on the range. It does help to get it on paper just start out at a shorter range then work your way up to 100 or 200 yard

5 star for the price, but: this is not professional tool! lower your expectations

Works like a charm and helped improve the accuracy of the rifle for target and big game shooting.

Works pretty well as far as I can tell in my apartment. It's pretty bright. I Will update my review if I experience any issues. There is no on/off button and it is on as soon as you put the batteries in. I solved this problem by putting a small piece of paper between the 2nd and 3rd battery before screwing on the base.

Very bright laser, set in my rifle very quickly with this bore sighter Excellent value
