"I bought a total of 6 or 7 of these in different cal for the many different guns I have, and I can't say they are worth the time to use them nor the money I paid for them... At the end of the day you still have to shoot the gun to bring the sights to zero and if I have to do this anyway - why buy a cheap bore sight? Live and learn."

"I bought this to sight in my Mosin 91/30, and it just doesn't work. While it says it'll fit, the laser is loose in the chamber, and the light diffuses going down the barrel. It takes putting a screwdriver down the action to get the light to a dot out the barrel. You have to do it in a darker room to see the dot, and it has to be done at 25 yards. Wouldn't recommend this."

"The sight itself is pretty nice. Chambered in no problem. An on/off switch would have been nice. The only problem I have with this sight is the batteries. They died in about 15 minutes. I searched through several stores and couldn't find any more. I looked online for the batteries and could only find them shipping from China. Other than the battery problem, the sight is very nice."
