Geissele Automatics, Ultra Duty Takedown Pins, Fits AR-15, Matte Finish, Black, Checkered - SKU: 05-1086 - UPC: 817953026977
Product Description
The Geissele Automatics Ultra Duty Takedown Pin Set in Black (05-1086) is a premium, hard-use replacement pin upgrade engineered for standard Mil-Spec AR-15 lower receivers. Designed to overcome the frustrating, smooth surfaces of standard factory pins, the Ultra Duty set features heavily checkered pin heads that provide positive, non-slip thumb placement for fast shotgunning and field stripping of receiver groups under adverse conditions.
Precision-machined in the USA from ultra-durable stainless steel, these pins are finished in a tough black oxide coating to withstand chemical solvents, moisture, and extreme abrasion. Extended pin head profiles allow for effortless push-through manipulation—even when wearing thick tactical gloves or operating in wet, freezing environments—without protruding far enough to snag on gear or slings.
Complete with replacement detents and detent springs, the Geissele 05-1086 Ultra Duty Takedown Pin Set delivers precision pin-to-receiver tolerances that reduce receiver slop, eliminate unwanted play, and ensure smooth, bind-free rotation during cleaning, maintenance, and tactical staging.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for standard Mil-Spec AR-15 lower receivers (0.250" pin diameter).
- Verify host AR-15 lower receiver is completely clear, magazine removed, safety engaged, and chamber confirmed empty.
- Depress existing pivot/takedown pin detents using a punch tool and remove factory receiver pins.
- Install front pivot pin detent and spring into the lower receiver channel using a specialized pivot pin installation tool to prevent detent launch.
- Slide the Geissele Ultra Duty front pivot pin into place, ensuring the detent channel aligns with the detent pin.
- Insert rear takedown pin, detent, and spring into the rear receiver channel, securing with the endplate and receiver extension buffer tube before torquing castle nut to 38-40 ft-lbs.
