The forearms on my Marlin and Winchester lever guns are bedded to both the barrels and receivers to eliminate all play. They are also well sealed inside and out and on the ends with spar polurethane. They shoot exceptionally well {under an inch for 3 shots at 100 yards.} don't swell or change point of impact in the rain or string shots when the barrels get warm. The notion that forearms need to be loose for good accuracy and to not string shots is complete bullshyt and I've experimented a bunch with these things.
