Question: Does this bore sighter use a CR2 battery or a CR123 battery or a CR123A battery ?
Document: Lazer bore sighter is ok for the money. The plastic bore adapters leave something to be desired. The lazer works ok, but the plastic adapters allow some movement of the lazer.
this unit could use a little more attention during the manufacturing process. It holds up alright for basic use but the battery compartment is very loose and often times it shakes loose while trying to sight in your scope. Overall it is good though, the green makes it very easy to see during anytime of day and long distances.
Took a while to get this and once it arrived the battery was DEAD. then once I bore sighted everything I went to the range and low and behold everything was way off. never again
I am a new gunsmith and have need to site in scopes I do most work at night and for that red lasers work fine but I do have day work that can't wait and that's where green is great. I can spot the dot at a 100 yards and set scope, in the sunlight. amazing!Highly recommend this bore sighter
Item works and is easy enough to use. However, the inserts for the barrel are not sized appropriately. They are all slightly smaller than 9MM, .40, and .45. To overcome this, I found nylon bushings at the local hardware store of the proper size (tighter fit), and now it is centered and works great.
The bushings are suppose to be slightly smaller. Once you have the "slightly" smaller bushing installed & inserted in the barrel you twist the bore sight & the bushing expands inside the barrel & gets tight.
When I put the battery in the unit it caused the laser mechanism to move to the side. The spring for the battery was so stiff that the tiny circuit board in side shifted to one side and caused the wires to come off. I returned it for a replacement. The new one is much better. The spring is not so stiff that it bends the tiny circuit board.
This is a good universal boresite. It fits the major rifle calibers, but I was a little disappointed it would not fit my 380 ACP. Oh well. The green laser is very bright and visible at 100 yards in the day. I've seen it about a mile or more at night, but its basically a beacon then. Two problems: the spring in the battery compartment is finicky, so it will go from full power to mild to off at the slightest bump.
Was looking at a cheaper red dot sight but was told the green dot would do a better job esp in daylight and the info was right on.Was definitely worth the extra $ works great.
Utterly disappointed. Intermittent switch that would not activate at least half the time. My 9mm collet split on four sides as it was screwed into the boresight for very, very slight tension. Not enough tension to allow it to center. I'm assuming the others will fail as well.Stay away from this useless item. You'll be sorry, I promise!
Answer: no
