  1. Thanks for the explanation of why you need to screw and unscrew the barrel nut 3 times! I always did that step but I really didn't know why you need to do it!šŸ˜ Great complete detailed video!!! Thanks again!

  2. Cool!!! Just got my AR 45 last night wondering where the hell my barrel nut is located……now I know!!! My first AR. Much lighter than my L1A1 and my Frenchy. Yes….I am a big 308 fan.

  3. Thatā€™s the main difference between men & women, we buy parts/guns even when we donā€™t have the money & women can stay patient & wait until they get a good deal šŸ˜†. Great build, it looks good.

  4. "just watch a girl tighten up a barrel nut"……Yeah baby. But I am just starting my first ever AR build. I am in the buying parts phase. I decided on 30 Luger of all things. Mostly that the ammo is cheaper than 9mm and can be found. I can switch to 9mm when and if things ever calm down. Glad I found this video
