Impact 737R firing pin replacement
- Thread starter phlegethon
- Start date
You have to push the shroud down towards the tip of the firing pin (loading the spring), so that the sear sticks out the back. There's a little retaining pin you have to pop out.
OK, so I assume you can get down to that piece.
Now you just need to get one of these. They are not expensive.

OK, I got it. I had read about a procedure where you cut off a 223 case to make a little shim to keep the spring compressed, but it had sounded like you had to remove the bolt shroud before doing that. I see now that if you put in the shim and unload the spring, the other end of the firing pin comes out enough to remove the roll pin that retains it.
You do need the bolt disassembly tool for this (well, it makes it a lot easier). This is the size of the cut off 223 piece:
Then you reassemble it this way:
And then at the other end after it’s screwed in, you can access the roll pin.

Ran into this exact issue a few months ago, and picked up a couple tools to help the process. These work so well, I just keep them in my range bag, and can now replace the firing pins if they ever go down in the field.
The instructions to replace the firing pin are exactly the same as the 700 firing pin assembly, and there are lots of Youtube videos on how to do that.
I also contacted Impact directly, and they use/recommend the exact same tools.
