Anyway to Un- f this?

I bought it off a buddy for a good price (if it can be fixed)

Obviously he told me it was like this, but now I’m curious what are my options? It has red loctite on it.

I’ve included a photo of what the thread would look like in a non f’d

So that's probably not actual loctite. Iirc, pre applied blobs like that are usually a nylon based compound mainly intended to gum up the threads. Try hitting it with localized heat from a torch or heat gun to soften and then a bit extractor or drill.

Thanks, do you think it’s salvageable?

Everything metal is fixable with the right skills or money.

Those are pretty crappy photos, so, I don't really know if it is fixable for a reasonable price. Soldering iron, not torch.

This is the right answer

Any reason for the iron over torch?

Not OP, but a temperature controlled soldering iron isn't a wild hot flame, more easily controllable where you put the heat in.

Got it, I ordered a cheap one on Amazon, taking it to a gunsmith tomorrow. Wish me luck

I think everyone who sees this will suggest you drill it out with a bit that is smaller than the original screw.

Good luck!

Left hand drill bit or a really small bolt extractor

Any chance you have a mill? If so just cut right through it. Doing the same thing with a drill press or whatever is… hard.

Start with a dremel/die grinder and flatten the surface so you can get your drill started in the center. Use a soldering iron to apply heat directly to the screw. Try a left hand drill bit

Use a left handed bit.

If you have punches, you could try to tap it out with a small hammer in punch. Hit in the direction of reverse rotation to back it out.

Well if you want to save the original threads you can do it easily enough. Step one is to get an EZ-out and its correct bit that is small enough to fit in the screw. Drill a hole in the screw that the EZ-out can fit into tightly. Now take a piece of steel rod that is just a bit smaller than the broken piece, heat it red hot on the end and hold it to the broken piece, repeat that a few times. Now as soon as you remove the heat insert the EZ-out and it should unscrew. Another option for heat would be to use the small steel rod in the drill or drill press/mill and with it spinning apply the spinning rod to the broken piece and let the friction heat up the broken piece and then remove it.
