I'm not worried about them fitting their brackets, Wayne. I've not made brackets yet.
No, I tell a lie, I made brackets x2 a long time ago, but they wouldn't fit anything bigger than a broom. Call them a test run.
The sight asembly is 90% together now.
I still need one last, but significant piece. It's the one that makes the lateral adjustment possible. If I can't find one, I have to make one. I really don't want to do that.
