Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum with M4 feed ramps and an anodized finish, and it includes the forward assist assembly along with the ejection port door, rod, and spring. It's paired with a 10-inch ultra-lightweight minimalist M-LOK handguard with a partial Picatinny top rail, built without anti-rotation tabs for a slim profile along the barrel.
