I have the Hawke Vantage Red Dot 1x20, 9-11mm. I like the style of how it fits and just gives enough space to get the mag in under it. Not sure I’d trust removing and refitting without spending some time to check the zeroing before shooting but maybe it will work if you mark the position and be careful with how you store the scope.
Great video on trigger springs, looks a bit tricky but I’m thinking of giving it a go. Small springs always seem to have a mind of their own when I try things like this, maybe a magnet next to the spring as it’s removed could be an idea.
