CNC machined from 7075-T651 aluminum. We have tightened up our tolerances significantly over a standard cast upper. We have designed our uppers to fit our lowers extremely well but they are compatible with most cast lowers. Comes with forward assist and ejection port cover installed. The perfect compliment for those wanting the most precisely made upper available.
