Rise Armament Upper Parts Kit – AR-15 Complete Assembly Components

The Rise Armament Upper Parts Kit provides all the small components needed to complete an AR-15 upper receiver assembly. This kit includes the forward assist assembly, ejection port cover with spring and C-clip, and all necessary roll pins, eliminating the need to source individual parts from multiple suppliers. Ideal for builders completing a stripped upper receiver or replacing worn or damaged components during a rebuild.

Manufactured from mil-spec materials with a black oxide finish for corrosion resistance. Installation requires basic AR-15 armorer knowledge and standard punches—the forward assist and ejection port cover are straightforward to install for anyone familiar with AR-15 assembly, though first-time builders should reference installation guides for proper roll pin staking techniques to avoid damaging the upper receiver.
