First off, another great review Joe! SWFA scopes get many rave reviews on AGN, so many in fact that I bought one. As nearly all of my shooting is done on my home 53yd range I figured that a good solid fixed power scope would be a good choice. I got the SWFA 16X mil-quad. After mounting it was immediately apparent that the target image was "cloudy". Not nearly as sharp as my Argos or Aztec set at 16X. I thought it must be defective and sent it back requesting they check it over and send me a 16X MOA-Quad. Same disapointing result and SWFA said there was nothing wrong with the scope I returned. I do shoot out of a window in a warm room into very cold air and there are "heat" waves that cause some visual disturbance but target clarity is still much better with the 2 variables mentioned. Could I have not set these fixed power scopes up correctly? Uj
