Geissele Ultra Duty DDC Lower Parts Kit w/NO Grip 05-435S

Geissele Ultra Duty DDC Lower Parts Kit w/NO Grip 05-435S comes with all the internal parts needed to complete or rebuild an AR-15 lower receiver, minus the pistol grip, so builders can drop in whatever grip actually fits their hand.

This Geissele Ultra Duty lower parts kit includes Geissele's Maritime Bolt Catch, known for its aggressive texturing and extended paddle, plus an Ambidextrous Super Configurable Safety that lets the safety levers be swapped and exchanged with a satisfying, positive tactile click in both safe and fire positions. The takedown pins and magazine release button share the same tank-tread texturing as the Maritime Bolt Catch, giving the build a cohesive, deliberate look rather than mismatched hardware.

Key components - pins, springs, detents, and the bolt catch — are machined from stainless steel for a longer service life and better rust resistance under heavy use. The Ultra Precision Trigger Guard is a separate story: 5-axis machined from a solid block of 7075-T6 aluminum and finished in Desert Dirt Color, giving this Geissele LPK an enlarged, glove-friendly opening that standard mil-spec guards don't offer.

This Geissele Ultra Duty LPK hands builders every internal part a lower needs, minus the one part everyone has their own opinion about.
