Geissele Automatics Standard AR-15 Lower Parts Kit w/ Grip (No Trigger/FCG) - 05-987 - UPC 817953025284
Product Description
The Geissele Automatics Standard AR-15 Lower Parts Kit with Grip (05-987) is a premium, duty-grade lower receiver hardware kit designed specifically for builders and operators who intend to install a custom aftermarket trigger. By omitting the factory Fire Control Group (FCG), this kit eliminates redundant component costs while delivering Geissele's legendary precision engineering across every pin, detent, spring, and manipulation control.
Every small component in the 05-987 LPK is manufactured to strict military-specification tolerances from high-grade, heat-treated steel and finished in severe-duty black oxide and manganese phosphate coatings for superior wear and corrosion resistance. The kit includes Geissele's standard textured safety selector, bolt catch assembly, magazine release hardware, pivot/takedown pins, buffer retainer, and a textured A2-style pistol grip with mounting screw and washer.
Ideal for staging custom AR-15 rifle builds featuring Geissele SSA, SSA-E, or SD-3G triggers, this complete non-FCG lower parts kit ensures smooth mechanical function, proper detent spring tension, and long-term cycling reliability for personal defense, competition, and tactical platforms.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for all standard Mil-Spec forged or billet AR-15 (5.56 NATO, .223 Rem, 300 AAC Blackout, 6.5 Grendel) lower receivers. Note: Does NOT include a trigger or hammer (Fire Control Group). Designed for use with standard 0.154" pin diameter triggers. Takedown/pivot pins fit AR-15 receivers; large-frame AR-10 receivers require platform-specific pins.
- Verify stripped lower receiver is clean and free of burrs or excess cerakote finish in pin holes.
- Install magazine catch, bolt catch, pivot/takedown pins, and buffer retainer pin with supplied springs and detents.
- Install your choice of aftermarket 0.154" fire control group before installing the safety selector and securing the pistol grip.
