The Geissele Ultra Duty Lower Parts Kit caters to the needs of the most demanding operators, providing all the internal components required to assemble or refurbish your lower receiver. This premium LPK showcases Geissele’s proprietary designs, meticulously machined at our facility in North Wales, PA. Key elements are crafted from Stainless Steel, ensuring an extended lifespan and minimizing the risk of rusting or failure, even in extreme conditions or heavy usage.

Included in the Geissele Ultra Duty LPK are standout features such as our Maritime Bolt Catch, renowned for its aggressive texture and extended paddles, and our Ambidextrous Super Configurable Safety. This safety mechanism allows for easy and secure interchangeability of safety levers, delivering a satisfying tactile feedback when transitioning between safe and fire positions. The takedown pins and magazine release button boast the same robust tank treading as the Maritime Bolt Catch, ensuring a cohesive aesthetic for your rifle.

Additionally, the Ultra Duty LPK features Geissele’s Ultra Precision Trigger Guard, meticulously machined from a solid block of billet 7075-T6 aluminum using 5-axis machining techniques, and finished with Type-3 hardcoat anodization. This ensures that your build stands out from the rest with unparalleled precision and durability.
