You are correct sir!

After looking at it I need to cut the rear surface a bit , the magazine adapter has a step in it so a little more off the right side than the left.
Need to eyeball it how far forward to cut it and where the end of the cover rests in the closed position.

Not sure if the lip of the cover is slightly behind the top detent or if it covers it.
