Confirm Your Zero
Every gun owner should spend some time and check the zeros on their rifles.
It’s easy to do with a variety of targets. Anything from paper plates to military style targets can be used. I like the standard 25 meter M-16 zero target. Use it at any distance you like, not just 25. I use them at 100.
So whether it be zombies or raging radical Islamists, you know you’ll good to go.
