AR-15s

I use the 2 rule except for the 15 round mag that is loaded in my CZ75 compact I carry daily. We weighted a G19 and the CZ with same amount of rounds and they were about 3 ounces different. Rather carry a metal framed sidearm… As for AR’s, cheapest I built one from online/local sources was 425 bucks from an 80% lower. On the other hand, you can spend 1000’s on a super nice one.
