I did the fighting rifle class this past weekend with the guys from Tactical Response in Bastrop. There are a few points in my mind that stick: Mark your mags: Trying to figure out which ones are yours when they are piled up on the ground isn't any fun. Use red or orange electrical tape and a sharpie. Or a paint pen. Bring spare mags: Five is the recommend number, but I brought seven, which is good because one of my mags puked its guts on me. Your shit will get scratched: If you bring a range/safe queen with you be prepared, you will be rolling around in the dirt/grass/cow shit, whatever is on the ground. Don't be a bitch: If you fuck up, you'll get yelled at for it. Personally this makes me want to push harder, but if you have sensitive feelings, or can't accept when you are wrong, you will not have fun. Sun block: I forgot mine the first day, now I look like hellboy. Wolf ammo: Great in an AK, fucking shit in an AR. Even if you think you have pushed your AR hard enough at the range, you haven't, your AR will choke on that Russian garbage. I had to learn this the hard way. Pistol holster: You can bring an IWB holster, but if you have an OWB, bring it instead, makes it easier (at least for me). Overall it was totally worth it. If you expect to be able to defend yourself with your rifle at some point your life, take this course, they teach some good shit that I believe can save your ass if you apply it properly.
