Eotech has a recall on their sights because of POI shifts. I had the swing away magnifiers as well. My two started floating their POI's and I was missing on standing broadside shots at 100yds off a tripod! Eotech very admirably gave me my money back on them after almost two years and I switched to Leupold VX-6's in 2-12 power. Now I'm shooting ragged holes and have a lot more confidence. You can't argue with 12-power optics when you're trying to shoot a small group.
