  1. Please don't do another build video. I lost count on how many things you did wrong and stopped video on the backwards castle nut wrench. (Which as a result of being backwards slipped off and damaged the nut.

  2. this is a really great video. You explained everything in details and it was not hard at all to understand how this was built. This video helped me build my first ar and i want to thank you for the ar lesson there. Once again, thank you for the video!!!

  3. Moose, I watched all 4 vids, you did a great job in my opinion. I am disapointed that you did not do a video of building the upper. Do you plan one soon? BTW your choice of music was great , I very relaxing and helped to keep me focused on the action taking place

  4. you did great except for 1 thing …. what was the point of the tape over your serial # in the other videos if you don't do it here???? this video left me thinking "if someday i can not work on my own AR, i want you doing it for me" …you are really good in my opinion. thanks for letting us all watch you

  5. OK 2:20 in and im convinced this guy really know NOTHING about ar15's! an AR does not have a "slide" that is the bolt catch/release…and you don't need a diagram to tell you where each spring or pin goes…it's pretty self explanatory!

  6. Very nice video! Like the background music, not like other with hard rock music that I can't hear a darn thing they are talking. I don't care about the name of all them parts but I learn more from this video than other "pro". Thanks and keep up the good work!
