The guys at Tactical Rifleman have done a great video on how to setup your AR and some rifle shooting tips. Want to know the best way to set up your AR? You don’t have to upgrade to this year’s “latest and greatest.”
I had it taught to me, year’s back, that “you don’t need a new gun until you can out-shoot the one in your hands.” Do you really need a gun that’s capable of .25 MOA groups when you (as a shooter) are only capable of shooting 2 MOA groups?
Do you really need this year’s “fastest Shotgun” when you drop half the shotgun shells while loading on the move in a 3-gun competition? Master what you have. When you can outperform your gear; then you upgrade.
