If you're willing and it's not too personal, would you share more about your experiences using the AR-15? My father was in the military and I only ever saw his service weapon once. If it was present in our home growing up, I never knew. I mention this because I find that getting the perspective of people who have actually had to employ weapons for their original purpose adds a lot of richness to these discussions. Thanks in advance for sharing.
