This video explains the importance of proper red dot sight zeroing for firearms. It highlights the common mistake of zeroing at 5 yards, which leads to inaccurate shots at longer distances due to the sight's height over bore.

The Kel-Tec P50 is a unique firearm chambered in 5.7x28mm, notable for its extremely lightweight design and surprisingly low recoil, even with a 20-round capacity.
