Come check it out, its a great time and a great group of guys. The full rules and everything is on their website (as well as a forum), but the basics you need are:
A rifle with sling
A pistol with good holster
A way to carry a spare mag for each
Dress for the weather
The fancy rigs some guys run are cool but not needed. If you look at when I'm entering the door, I just have a kydex holster on my side with one rifle and one pistol mag.
The guy in white is carrying a shoulder bag designed for gun magazines. It holds 4 rifle mags, 3 pistol mags, and enough room for snacks, first aid kit, tools, etc. I have one as well but prefer the belt holster for these matches.
Come check us out!!
