Should these nailer be able to drive 3 1/2" nail and coutersink the heads. Mine would not successfully sink them every time so I rebuilt it, all new seals, bumpers. It still will not sink them fully and if trigger fired it occasionally double shoots. I have tried pressures up to 120 psi with 3/8" hose and fittings. It works better if I put all my weight on it and trigger fire it than if I hold down the trigger and bang the gun on the work.
