Frankly I wished they had taken their Phaser Remote and made a B&W version of it rather than the mood rock but that is just me. It would be great if someone figured out how to put the rising site in while still being able to keep the rest of the functions.
Chris, just noticed your post here hence the delayed response. . .
Here are a couple of photos I took while it was apart that may help you. Unlike the P1 from WandCo's Universal Phaser Remote this one comes apart very easily [SNAP-FIT] without any chemical welds or glue holding the parts together. I used a pair of side cutters to cut out the plastic dial visible next to the battery in the first photo. I replaced it with a cut down aluminum dial like those used on mid-grade P1's.
