Poor switch quick fix - BARSKA 1x 20mm Dual Mount Scope w/ Dovetail/Weaver Base

Red/green dot sight was trash, right out the box. Reticle switch was tight and was failing to hold power at dialed level Whether green or red. QUICK FIX = Cordless Drill + large Flat/Pan head screw bit. Using a steady hand, screw the battery cap with battery installed in clock wise motion. Build a moderate to brisk pace 5-10 seconds or as needed and dial should feel more crisp and illumination settings should hold as desired. Purchased for dovetail rail on pellet rifle. Current use is a 80lb pistol bow. Works nice now. Pretty good sight. Compact and low profiled.
