Take-down is so easy....once the mainspring is out, the upper falls right off, yet once back together shoots tight groups as far as a .22 is concerned. Laseraim Illusion red dot. Looking to possibly trade for another 22 pistol, will always consider offers. New rebound spring. Readjusted sear spring (Trying to get a new one from Ruger) I paid about $40 for mount and $60 for red-dot. Cash price breakdown: $325 without scope and mount $380 with scope and mount I found a new toy I NEED!
