I have been putting my new Merkel 140-2 450-400NE through the paces and discovered it shoots low except with the 75 yard leaf, which is well forward of the 50 yard leaf and express site. This got me thinking. I know it is sacrilege, but I would experiment with a red dot type optic. The Merkel 140 has a removable dovetailed plate on the barrel where it meets the receiver that appears to be designed just for this purpose. Here's the problem - I called technical support at Merkel in Alabama, and they didn't know what optic or mount system it was designed to work with! Has anyone installed anything using that plate on their Merkel 140? I know I can send it off for expensive work, but it seems so simple with the right product. It must have been made to accommodate something! I would like to try a red dot or a ghost ring/peep site on that plate. Thanks for your thoughts!
