Gringo -
I reckon that'll work. <grin> Glad you were able to get it apart. Try to get it back together AS TIGHT as it was.
I've been using 760s & M 6s for a long time which involved several rifles. Fortunately I've never had one that rattled. I had a friend in La. whose 760 rattled. I would get one fixed IF it rattled too.
Congrats
Jerry
