Adjustable rear sight for EAA Witness?

[Buck13]

I have a Wonder Finish Witness, the base-model steel frame, with a fixed rear sight (bought Dec 2012, square slide, I think) that has always shot a little low for me at 25 yards.

I'd like to play with it at longer ranges on steel targets, up to 100 yards. Is there a replacement adjustable rear sight to fit that dovetail that won't bottom out too much higher than the factory sight but can go up enough for long range?

The LPA adjustable sight is made for the Witness, check EAA or Henning ( henningshop.com )The sight might also be available through Brownnells. I just checked, the LPA is also available from Midway USA. Be sure you specify the TR model, which is intended for the original front sight.
