Description

The Super Duty Complete Upper Receiver delivers next-level AR performance and comes fully equipped with Geissele exclusive features. The barrel is precision machined and cold hammer forged out of the highest quality steel, featuring a manganese phosphate coat and a chrome lining for excellent resistance to the elements. One of the Super Duty Upper Receiver’s more notable features is Geissele’s own Reliability Enhanced Bolt Carrier Group. This BCG is Nanoweapon coated and features a gas key that’s been properly staked, torqued, and is lined with chrome. Adding to the Reliability Enhanced Bolt Carrier Group’s performance is a cam pin machined from H13 tool steel with a Nanoweapon coating for corrosion/wear resistance, and extended upper rails are included to provide greater stability and improve feeding reliability. Another feature of the Reliability Enhanced Bolt Carrier Group is its Stressproof Bolt, which is precision machined from Carpenter 158+ barstock – a material that is cleaner, has less impurities, and offers greater strength and fatigue resistance. The Super Duty Upper Receiver is completed with a MK16 Modular Rail that’s been perfectly mated to the upper receiver to eliminate and risk of rail rotation. The MK16 rail runs the length of the receiver and fore-grip, and provides more than enough space for iron sights, red dots, scopes, and clip-on thermal/night vision devices.
