Document: The 7.62 x 39 mm Caliber Cartridge Laser Bore Sighter that I bought is exactly what I expected. I love it, RJ
I purchased another type 7.62 x 39 bore sight laser with case and it was much more exspensive. The case was not necessary. Unit came with batteries.

This device does exactly what one expects. It is a good device for initially aligning the bore of a 7.62 x 39 mm rifle to a telescopic, modern holographic or laser sight. As advertised it will get you close enough to fine tune the sights on the range. The laser is activated by turning the base of the cartridge. It does dim after what seems like a short time. I wish it would run longer and just let me replace the batteries.
I am going to try to write the most helpful review of this product as I can. DO NOT BUY, If you want to know what it feels like to be an owner of this 7.62 x 39 laser bore it can happen very easily. Just take 15 dollars out of your wallet and put it in the garbage disposal afterwards take out another 10 dollars for replacement batteries and put that down the drain as well.
These laser bore sights (both 7.62 x 39 and 5.56) are misaligned and very blurry, causing light refraction within the barrel and causing a prismatic effect upon the target. The laser kept shorting out as well, and could not stay on without extensive fiddling of the cartridge inside the chamber. The bore sighting device wiggles quite a bit in the chamber, so every time you insert the laser the point of impact is different. Totally useless product.
Works well for me because I have multiple 7.62 x 39 weapons. Set up is fast and point of aim has not proven to be an issue as of yet.
It arrived quickly! It came with three batteries. I put them in and it worked fine. I also put it in my 7.62 x 39 caliber weapon and it did it's job. The laser was bright on the wall. Satisfied customer here.
WIth 7.62 x 39 you will reach out and touch someone. For the price its a good investment and the best way to obtain extra batteries which you may find in more dollar stores or Big Lots for cheap. It will help your shoulder and at the cost of ammo why not have one in your tool kit as it is clearly marked as 7.62 x 39 on the side.
I ordered A 7.62 x 39 mm Caliber size for my SKS. I recieved a .223, after shaking my head in disbelief, I gave it to my friend who has a AR-15. It works well from what I see. Only reason I gave them a second star.But otherwise total fail in the size department.Follow up:I purchased this while on sale, and I am happy to report that they refunded me the money.
