Garbage - SSI Sight-Rite Deluxe Laser Bore Sighter for Pistols, Shotguns and Rifles

I purchased this after waiting months for the Leupold Zero boresighter. I should have kept waiting.. First, it barely (if at all) even turned on. I had to shake the sholw laser in order to get it to even power on. And the O-rings that come with it are a joke. It says CLEARLY covers ALL calibers from .17 to .50. I guess 762X39 isn't included in that as the laser would barely even sit in my rifle. Save your money and wait for the Leupold...
Pros: none
