  1. Great job!
    You must me a teacher in your other life!
    My favorite parts are when you say "hold on this is being……whatever" (I don't feel bad when I hit a snag there as well)
    There are lower videos that run 7-10min. (not for a first timer)
    I've watched (paused, rewound ) your video at least 10 times.
    Very well done, Thank you!

  2. Video is very much appreciated. I do have a pointer to throw your way. When you're installing the buffer tube, and are ready to insert the detent and spring for the rear take down pin, simply tighten your castle nut down to touch your plate to the razor blade prior to pulling the blade off the spring. That will stop your spring from having any room to wiggle out like they do.

  3. By far the best video on assembling a lower I've seen. Very detailed. I'm getting ready to assembly my first one with the Palmetto lower kit and this was very helpful. Thank you!

  4. I've built about 6 lowers. I got tired of worrying about breaking off the tab over the rear of the trigger guard so I found a pack of hex screws on Amazon and just put one on each side of the guard. Makes it alot easier. Thanks for the video. Love the channel.
