Yes, I was writing primarily to 'meatofman24' having the issue with his sight not holding zero. I agree with you on the battery issue. See his post in msg #116 above.
As an aside, I have a Wasp I've never mounted but did install the battery on 12/26/21 due to this very thread. As of today, 3/1/22, a full two months, it's still going strong. But mine was bought from Springfield Armory well over a year ago, just had not installed the battery till this thread. So, more than two months ago it went in and still today going strong. I've made it through the 'one month till dead battery' issue, so I guess we'll see.
