Geissele Automatics was established in 2004 as a manufacturer of trigger mechanisms for the AR15 rifle. Rely on Geissele when you expect superior performance, quality, and reliability. The Geissele Ultra Duty Lower Parts Kit is made for the most demanding operators and includes all the internal parts necessary to complete or rebuild your lower receiver. This top-tier LPK features proprietary Geissele designs, machined with great care at our facility located in North Wales, PA. Key components are made from Stainless Steel, which offers a much longer lifespan and a much lower chance of rusting or failing in extreme conditions or under heavy use. The Geissele Ultra Duty LPK includes our Maritime Bolt Catch, famous for its aggressive texturing and extended paddles, and our Ambidextrous Super Configurable Safety, which features the ability to easily and securely swap and exchange the safety levers plus provides the end user a satisfying and positive tactile feedback when the safe or fire position is engaged. The takedown pins and mag release button feature the same tank treading as the Maritime Bolt Catch, giving your rifle a tasteful and cohesive look. Included in the Ultra Duty LPK is Geissele's Ultra Precision Trigger Guard, 5-axis machined out of a solid block of billet 7075 -T6 aluminum and Type-3 hardcoat anodize to ensure that your build stands apart from any other.
