Rise Armament Premium Lower Parts Kit Features The Rise Armament Premium Lower Parts Kit goes beyond a standard LPK by including upgraded Rise Armament components alongside the essential pins springs and hardware needed to complete an AR-15 lower. The RISE Ambidextrous Safety Selector features captured detents and interchangeable paddles giving both left and right-handed shooters a natural ergonomic safety throw at 69 degrees. An enhanced bolt catch is included for reliable lock-back and easy release addressing a common point of failure in lower-quality kits. A swing-open trigger guard machined from aircraft-grade aluminum replaces the typical stamped steel guard with a stronger more refined component that still accommodates gloved hands. An oversized magazine release button with enhanced texture improves control during reloads making it easier to drop magazines quickly and consistently under stress. The 23-piece kit includes every pin spring and detent needed for a complete lower build including takedown and pivot pins trigger pins buffer retention hardware and all associated springs. Builders assembling a lower from a stripped receiver will find everything necessary in one box eliminating the need to source individual small parts separately. Anyone building or upgrading an AR-15 lower who wants premium ergonomics beyond a bare-bones kit will find this Rise Armament set a strong foundation available for sale at GrabAGun.
