home depot can help - 5.98 for Blue Magnetizer/Demagnetizer
Those shitty demagnetizers don't work on firing pin or things larger than a tiny screw or paper clip. I've tried several using several weird techniques but it just simply doesn't do jack.
I agree, which is why I bought six when they were $115
But...
$190

= not even close
Gettin' down innagrass.
Let's Go Brandon!
I respect SOLGW for listing all those specs.
I don't understand the "personal preference" part. It's not suppose to be magnetic, that's not a preference; that's the spec. Somewhere through the manufacturing to shipping process it was handled incorrectly. I'd be irritated but at the same time if I couldn't de-mag it, I'd just get a new firing pin and be out the $7+shipping or at least go to the LGS. Most places carry AR small parts now.
