    Wow! The two day RX100 is already finished. I have taken a dozen firearm classes over the years, and I am a defensive handgun instructor. Have no fear, when you take this course you will become intimately familiar with your rifle. You will learn about your firearm and optic inside and out. Learn a skill, perform the skill, and then talk about it. Wash rinse and repeat. Next thing you know you are zapping spent shotgun shells at 100 yards nothin to it! I found Rex’s teaching method to be a very effective way for me to learn. Thank you TRex, family and crew. Two days well spent and I’m looking forward to the RX1000!
