Actually, three screws...The larger front one that holds the barrel to the stock and two smaller ones on the trigger guard...No real suprises except the front one is tightened good and tight with a larger screwdriver and the smaller ones on the trigger guard, just snug up good...I'm sure someone will chime in with the specs (I think its 65 inch pounds on the front and25-30 on the rear two)...I don't own an inch pound torque wrench...Just do it by feel....

btw...Tighten the front one first, then the rear two...

While you have it down, I'd clean the trigger area as well...
