....this time my Leupold 6.5-20 EFR. Will not hold zero any longer. Groups at 25 yds. approaching two inches with no repeatability. On the way to Leupold for repairs, another twenty bucks spent for postage. No problem, put the open sights back on for now. This rifle is very accurate and I am at no disadvantage with out optics. This little plate was no challenge at 40 yds. off hand. I installed the small dot post with corresponding rear insert. That rotating leaf kept moving due to weak retainer spring. I made a little plastic spacer washer to tighten it up from moving. With this virus thing going on, not sure how long the EFR will be in Oregon.
