The APE Hardened Steel Armature Pin is a direct replacement for your Tippmann A5 stock pin.  The stock Armature pins will wear over time and can cause inconsistent operation or firing of your E-Grip.  The APE armature pin is so durable, it will most likely be the last armature pin you’ll ever need!
 
NOTE: This will not work with Tippmann 98/Pro-e style markers
