HIPERFIRE’s AK pins feature chamfered edges for easy push-through installation into any AK receiver; no more hunting for the hammer and trigger holes, or the receiver hole on the back side. The pins are longer so they protrude slightly, making it easier to push them out during uninstalls. These pins especially compliment HIPERFIRE’s AK triggers that also feature US patent pending pin installation chamfers. The pins are compatible with stock pattern AK hammers and sleeved trigger subassemblies.
