Ultra Duty Lower Parts Kit

Geissele Ultra Duty Lower Parts Kit - Mil-Spec

The Geissele Ultra Duty Lower Parts Kit is designed for the most demanding users and includes all the internal parts needed to complete or modify your lower receiver. This top-of-the-line LPK features proprietary Geissele designs that are machined with great care at our facility in North Wales, PA. The key components are made of stainless steel, which offers a much longer service life and a much lower risk of rust or failure under extreme conditions or heavy use. The Geissele Ultra Duty LPK includes our Maritime Bolt Catch, known for its aggressive texture and extended paddles, as well as our ambidextrous, highly configurable safety, which allows for easy and secure replacement of the safety levers and provides the end user with satisfying and positive tactile feedback when the safe or fire positions are engaged. The trigger pins and magazine release button feature the same armored profile as the Maritime Bolt Catch, giving your rifle a tasteful and unified look. The Ultra Duty LPK includes Geissele’s Ultra Precision Trigger Guard, which is machined from a solid block of 7075-T6 aluminum using 5-axis machining and hard-anodized to ensure your build stands out from the rest.
