Rise Armament Premium Lower Parts Kit AR-15

The RISE Armament Premium Lower Parts Kit goes beyond a standard LPK by pairing all the essential pins, springs, and hardware needed to complete an AR-15 lower with a set of upgraded RISE components that improve function, ergonomics, and ease of assembly from the start. The ambidextrous safety selector ships with captured detents that stay put during installation, interchangeable short and long paddles for customizable feel, and a 69-degree throw for faster transitions without sacrificing safety. Enhanced takedown and pivot pins feature concave faces for easier pressing, beveled edges to prevent receiver marring during disassembly, and a tool-assist cavity on the left side for controlled removal with a pen tip or cartridge. The aircraft-grade aluminum trigger guard runs a swing-open design for gloved-hand clearance in cold weather. An oversized, precision-machined magazine release button adds enhanced texture for faster, more secure mag changes in wet or slick conditions. The enhanced bolt catch is larger and textured for quicker lock-back and release under pressure. All core springs, detents, and roll pins are included to finish the lower. Engineered and made in the USA.
