Question: will this bore sight work on a 3"1/2 inch pistol barrel
Document: 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.
It does not work like it should, totaly not accurate, the alignment is wrong and it's not a tight fit to the barrel
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
The rubber collets do not fit tightly in certain calibers. I stripped the boresighter with the screw trying to make it work in my 308.
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.
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
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.
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.
As with most items shipped directly from China it took a while to get here but once it arrived it worked fine. Very bright green dot (100 yards). Easy to sight in and accurate. Also worked on my .177 air rifle at 100 ft.  but had to compensate for scope height at that short distance.
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.
Answer: yes
