I just got a call out of the blue from Brownells. They said it was listed as 1/2x28 incorrectly. Should have been listed as 1/2x20. Offered a prepaid return label if it doesn't fit my needs. It's fine with me and I'm not returning it. I didn't ask about options for a different thread to see if any were available.

At any rate, some of you may get a call.
