Geissele Lpk Standard With Grip

The Geissele Lower Parts Kit with Standard Grip is a mil-spec–compliant collection of components designed for AR-15 builders who want to source their own trigger and complete their lower receiver assembly. Geissele, known for manufacturing some of the most respected drop-in triggers in the industry, built this LPK to give builders maximum flexibility: you get every other component you need to finish a functional lower, and you choose the trigger that matches your shooting style and budget. Whether you're assembling a precision rifle, a duty carbine, or a plinker, this kit covers the foundation.

The kit includes the grip and grip hardware, safety selector, mag release, bolt catch, buffer retainer, takedown pins, and all associated springs, detents, and roll pins. Everything is machined to mil-spec tolerances and built for reliable, smooth installation in standard AR-15 lowers. Since Geissele leaves out only the trigger, hammer, disconnector, and trigger pins, you have just what you need—no redundant parts, no surprises during assembly.

This is the right choice if you already have a trigger you want to run, or if you plan to upgrade to a nicer trigger group later. Geissele's attention to material quality and tolerances means you won't fight sticky safeties or rattling parts; everything will function cleanly the first time.
