Quality and Affordability by Jeff, Verified Owner, April 7, 2025
I make a point to change out my AR-15 firing pins after 2,500 rounds MOL. Discovered these TRYBE AR-15 firing pins on sale at Optics Planet. Glad I did! Everyone should stock up on these TRYBE pins that are affordably priced and quality manufactured...

Spec firing Pin by Sheepdog, Verified Owner, December 26, 2024
Everything I can determine on this pin it is right at mil-spec (length, diameter, base thickness). It fits perfectly in high end bolts (DD, BCM, LWRC). Will advise if things go south upon testing but for now I will leave it 5 stars.

Extra firing pin by bordy, Verified Owner, February 22, 2024
Keeping an extra firing pin in your oops kit is a very smart idea. Trybe makes an excellent product and they’re pretty fairly priced so I have one for every gun now
