STBA hammer and trigger pins for Tactical Innovations' STBA AR15 receiver pins sets.
If you have a receiver with STBA bushings installed and lost one or both of the pins, these replacement pins will get you fixed up. These hammer & trigger pins will only work with already installed STBA receiver bushings and will not work with GI receivers without STBA bushings installed.
Pins are shipped per PAIR. If you order one, you will get one pair of pins (2 pins).
