Nice set for a beginner build
Great experience will be back
USGreat parts kit!
Overall it was great. I loved the quality and style and ease of using parts. While I needed to drill deeper for trigger mechanism to work properly. He was great the only thing I had issues with was pin used to hammer into side of 80%. If I had to do it again. I would drill that hole just slightly bigger so pin would still fit snuggly with out marring finish on your lower. It was not a good fit and either hole was too small or pin was too thick in width. Otherwise it was excellent and I will buy again. Thanks so much!
