Rise Armament Upper Parts Kit is a 7-piece standard package for assembling an AR-15 upper receiver; it brings together the essential upper receiver small parts, such as the ejection port cover (port door) and forward assist, to ensure a purposeful assembly process. The package is designed for mil-spec AR-15 systems, providing the critical components needed for maintenance and assembly as a single unit.
The parts are made of steel and spring steel, featuring a wear-resistant black protective finish. The included springs and pins enable mechanically reliable operation, while the ejection port cover rod and e-clip ensure the cover stays in place. The parts are dimensioned to be compatible with mil-spec upper receivers, facilitating installation and ensuring fitment with most AR-15 upper receivers.
The forward assist assembly enhances the reliability of bolt closure in situations where the bolt requires mechanical assistance. The ejection port cover helps protect the bolt and ejection channel when the firearm is not actively firing, reducing the risk of contamination. The 7 parts in the kit cover all essential components for both the forward assist and the ejection port cover, eliminating the need for separate purchases.
