Gotical 30-06 25-06 and 270 Cartridge Laser Bore Sighter .270 Red Laser Boresight

I am very satisfied with my purchase of this device. I bought 2 and both were fine (one for .30-30, one for .30-06).The batteries are LR41 watch batteries, available at stores that replace watch batteries, or online. I had no issues with weak or dead batteries - the ones that came with mine outlasted my sight-in session. That said, when the batteries are in the device, the laser is on, so just take the batteries out when you don’t want it to shine. It is very easy to inadvertently put a battery in backwards, so if it doesn’t work at first, make sure you put all of the batteries in the right direction/orientation.This device does exactly what it is supposed to do, and for the price, it does it quite well: it shines a red laser beam down the rifle bore to the target down range so that you can then adjust your scope crosshairs to cover the laser “dot” on the target. From there, you have to actually fire a round or two to see where your point of impact is and then adjust your scope from there.Things to be aware of: The instructions state that you should not close the action with the laser in the chamber, “because it may damage the laser”, presumably due to the force of the bolt ramming fine. The fit of the casing in the bore was pretty good. However, what I noticed was that the casing will not fully and reliably seat so that the laser is always at the same point down range without some mild pressure behind the casing in the action- this is important so that you can have a stationary laser in the bore, not inadvertently wobbling around in there while you try to adjust your scope. For me, I used a spent casing turned backwards to just hold it in place with finger pressure while adjusting the scope crosshairs - easy peasy. Only required a couple of shots at 25 yards to get my rifle rough sighted and then a couple more at 100 yards to get it dead-on.

works as expected and made pretty sturdy

Once I ordered new batteries, the laser worked like a champ. Although mine took four batteries, not three as in the instructions on the item page, it sill fired right up and I was able to sight in the scope at 50 yards with no issues. Definitely recommend, but also recommend buying new batteries as well..

I got this today. I think the people need to realize that it is a bore sight. And work really well. I wanted it because I travel with my rifle and I wanted to make sure my scope doesn't get knocked off. I know my scope is dead on now. And this will give me confirmation when I take it out of the carrying case again.

Doesn't even fit in chamber properly so bolt cannot be closed. each time re-inserted provides different aiming point several inches off last position. Once machined to proper case length to fit with proper bolt lock up, still provides several inches of dot movement each time re-inserted. Laser obviously not aligned in cartridge. Not even good enough to get you on paper at 25 yds. Do not buy! I wouldn't even rate it a one.

Works great for the price.....dot at a distance over certain distance changes accuracy so maintain certain distance for accuracy

This worked OK.

This works great just do not close your bolt closing your bolt will lead to all kinds of problems
