Does the job - Osprey Global Red Laser Boresight

Nice little laser bore sight. The last one i had would come on accidentally in the case when the batteries made contact. The batteries were often weak or dead when u needed it. This one has a spring loaded cap that only activates the laser when you want it to. Very nice upgrade from my previous one. Gets the job done every time and so far havent noticed any reason not to have it. Will be buying more calibers from Optics Planet.
