I was shooting with my new Max-lite Sporting this past Saturday and out of the blue the top lever stopped locking open when opening the gun. I could "hold" it to the right and close the barrels and then release the top lever but it no longer stayed locked to the right when I open the gun. I've removed the trigger and stock and looked to see if there were any broken parts or springs but nada. So it's back to Kolar for a fix. Surprised to have a part fail in a new gun(12/15) build.
