Do I need to replace this gas key?

I picked up a Sionics NP3 bcg second hand and the gas key has minor damage around the gas tube interface. Do I need to replace the gas key or is it not a big deal? I checked it on my upper and it closes and didn't appear to get caught up on anything.

Does it go fully into battery? Put it in the rifle and try it out. Shoot it. If you have no malfunction then you probably don’t need to worry.

Yikes, must have landed just right on a very hard surface.
If it was mine I would replace it, or at least try to bend it back to normal, for peace of mind.

The fourth law is that a dropped carrier will land on its gas key just as sure as toast lands butter side down. It's a very common problem that can be fixed. If it's not hanging up there's no reason to worry about it.

What will happen is that your gas tube will start getting eaten away very slowly at the contact point. Too slow to notice most likely, but by the time you do notice, you will be swapping out your tube and key.

This is why BCGs with integral gas key are some stupid shit. One of the things IG had his classes do was to strip down the BCG and install the carrier only and run it back and forth with your pinky finger to feel how the key was engagng the gas tube, it should be super smooth with no hang-ups, I'd bet performing that test you'd feel it. I'd replace the key, the screws with some OCKS and stake it with a MOACKS.
