Overview of the Radian Takedown and Pivot Pin Set | R0077
The Radian Takedown and Pivot Pin Set (R0077) replaces the two pins that hold your AR15 upper and lower receivers together. Radian Weapons CNC machines both pins from high-strength steel and finishes them in black salt bath nitride, with the Radian logo engraved on each pin head.
Stock pins can seize in a tight lower, and a stubborn pin during cleaning or a parts swap wastes time and scratches your receiver. This set is built to come apart cleanly.
Easier Field Stripping
-
Dimpled tails accept a cartridge tip or punch, so you push the pin out without marring the finish.
-
Fingernail groove around the forward pivot pin head gives you a solid grip to pull it free.
Who It Serves
Patrol rifle armorers, law enforcement officers, and civilian AR builders use this set to upgrade or refresh a standard AR15 or M16 lower receiver.

Intended Users
Agency armorers use this set to service patrol rifles and keep pins moving freely during routine inspections. Law enforcement officers and military veterans who maintain their own AR15s use it to make field stripping faster and cleaner. Civilian builders add it to a new lower or a custom build for a finished look. Home defense and competition shooters use it to refresh worn or stuck factory pins.
Building from the ground up? The Radian Builder Kit includes this enhanced pin set, and the Radian Extended Bolt Catch R0323 pairs well with it on a lower upgrade.
