Excellent upper with tight tolerances. The finish looks good as well.

These are excellent finished upper receivers. The anodizing is impeccable, really a dark rich , thick silky smooth finish. Very few companies come close to the quality of these uppers at this price .

Built two rifles this year with the mega sets. I’m super happy with them. The fit and finish is just about as good as you can get.
