One of my least favorite things to do is sighting in my rifles. It’s something every gun owner should know how to do, but I never look forward to it. It’s not hard to figure out, it’s just a pain. I’m a fan of laser boresighters for my guns, even for my Mosin Nagant. I use this laser boresighter I got on Amazon. It’s affordable and saves both time and ammo.
They go for under $12 shipped on Amazon HERE.
