I recently worked on the trigger on one of my AR-15s and had my 'smith harden the surfaces of the hammer and sear since I'm pretty sure I broke through the original hardening. He used a product from Brownell's that he bought 30 years ago and that he said is no longer made since California decided it causes cancer.
I found this on Brownell's site, but it's out-of-stock.
SURFACE HARDENING COMPOUND | Brownells
Although the can looks similar, I don't know if it's actually the same stuff.
Are there other good products that would be available? I'm interested because it's a 140-mile round-trip to my 'smith and I have more work I'd like to do.
Thank you,
Richard
