Geissele Automatics, Super Duty Takedown Pins, Fits AR-15, Matte Finish, Black - SKU: 05-1087 - UPC: 817953026960
Product Description
The Geissele Automatics Super Duty Takedown Pin Set in Black (05-1087) is a precision-engineered, duty-grade pin upgrade designed to enhance the service life and operational reliability of standard Mil-Spec AR-15 lower receivers. Built to replace soft commercial steel or erratic factory pins, the Super Duty set provides smooth, non-binding rotation and crisp detent seating across thousands of upper-to-lower receiver separation cycles.
Precision-machined in the USA from ultra-durable stainless steel, these pins feature a smooth, low-profile extended head design that allows easy push-through separation without catching on slings, chest rigs, or tactical equipment. The black oxide protective finish ensures maximum resistance against corrosion, moisture, carbon build-up, and chemical cleaning solvents.
Including replacement stainless steel detents and high-tensile springs, the Geissele 05-1087 Super Duty Takedown Pin Set eliminates unwanted receiver play, ensures exact pin-to-hole alignment, and delivers long-term durability for duty carbines, competition builds, and tactical staging setups.
*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 brass punch tool and slide factory receiver pins out of the lower chassis.
- Install front pivot pin detent and spring into the lower receiver channel using a pivot pin installation tool to prevent spring damage or detent loss.
- Slide the Geissele Super Duty front pivot pin into position, making sure the detent track aligns smoothly with the spring-loaded detent.
- Insert rear takedown pin, detent, and spring into the rear receiver channel, securing with the endplate and receiver extension before torquing castle nut to 38-40 ft-lbs.
