M4 Hammer Install going south

Recommended Posts

Following the insertion of the USA M4 Hammer and when pushing on the "Trigger Pin Bushing", felt a little tension. Therefore I jiggled the hammer and applied pressure. With the applied pressure, the pin popped in. Felt great, then noticed one side was a pancake. There is no way the pressure I applied with my thumb could have caused that (at least my personal opinion)

Was it damaged from the use of the snap ring pliers? It's hard to tell from the photo, but the damaged end is the side that the snap ring installs on right?

 

Before you just order this one item. Consider what you need from Brownells so you can maximize on the shipping costs.

Don't know if damaged by snap ring pliers or when pressure applied to reinstall. Since I only pulled the pin just enough to install the new hammer, I have no idea when it occurred and yes it is the side that the snap ring installs on.
