Originally bought the Beamshot GB800, however it malfunctioned after extream M4 usage. Contacted Quiron direct, they explained that this unit is reliable for home or hunting conditions. However my requirements are much more extreme. They explained that the GB2000 would more than meet my requirements. Customer service was excellent. Turn around time was superb. If you have a JOB that requires hard usage you can't go wrong with this unit. And for those that had issues with beamshot, you have to be respectful, and truthful.
Pros: Works well under duress. Quick target acquisition
Cons: None at this time
