  1. Good piece
    It's on the tight end of tolerances but it could be my Blue Line lower. I'm sure it will break in after a while. Otherwise, purchase with confidence.

Pivot Pin

80% of 100
In stock

Your Upper is held in place by pins in the Lower at the front and the rear; this little fella is for the front and it is the longer of the two pins. It has a "D" shaped cross-section and only goes in the hole one way.

If you are frequently opening or changing your Upper in the field, you might like our Enhanced Pivot & Takedown Pin Sets.

  • Mil-spec

You get:

  • (1) Pivot Pin

Compatible with:

  • All Mil-Spec lowers
  • All Mil-Spec uppers
  • All Mil-Spec pivot pin detents

Installation Difficulty:

Tools required: Punch to remove

Installation notes: Other stores sell a tool to install this pin but it's not really needed, just use the side of the pin to depress the detent. If you take coffee through an IV you might have to come down temporarily to get the required steady hand.
