Review on Metabo HPT NR90ADS1 Pneumatic Collated: Power and Precision for Efficient Fastening by Brendan Thorpe

Use of 2" fence/gate nails causes this unit to frequently bind. Weed. The instructions say to drive a rod into the gun to move the hammer. The weapon was replaced after the first nail hammered caused a joint so strong that when a small sledgehammer hit a steel bar, I couldn't move the hammer. The replacement jammed a few times so I went back to the Revain and bought another shotgun.
