Replacement Cotter Pin for AR-15 Firing Pin

From the first time you’ve stripped down your AR15, you’ve probably learned to hate the firing pin retainer.  It can be hard to get out, even harder to get back in, it’s easy to lose and can be easy to break.  If you’re in need of a replacement, and your firing pin is free-floating, this replacement piece will serve you well.  This isn’t an off-the-shelf cotter pin from the hardware store; this is specifically made for the AR-15, and is compatible with any mil-spec bolt carrier group.

Specifications

  • Fits standard AR-15/M-16 bolts
  • Not a standard cotter pin – made specifically for AR-15
  • Durable, corrosion-resistant phosphate finish
  • Mil-spec dimensions
  • Made in the USA
