Developed by ARDEC, Geissele puts its own spin on Picatinny DSL, offering a family of Durable Solid Lubricant coatings that is an exclusive aspect of all upper assemblies Geissele makes.

Geissele applies the layer at much lower temperatures to ensure the metal beneath the coating remains unaffected. The resulting process ensures an unbelievable surface hardness almost equal to synthetic diamond and efficiently rejects carbon buildup, making cleaning and maintenance quick and easy.

This Super Duty entirely built upper receiver chambers a 5.56 NATO round and is features a chrome-lined barrel with a 1:7 twist, which provides remarkable stability of heavier rounds.

Featuring a new and improved 13.5" Super Modular Rail that affixes to the upper with a center aligning tab, the Geissele Automatics Super Duty AR-15 SMR MK16 mount process eliminates any rail rotation often experienced in other types of upper receivers.

The Geissele Automatics Super Duty Upper Receiver also includes their award-winning Reliability Enhanced Bolt Carrier Group, which is also Nanoweapon coated and made from Mil-Spec 8620 steel with a chrome gas key that already is appropriately torqued and staked.

Another essential feature of the Geissele Automatics Super Duty is the Cam Pin, which is machined from a type of medical steel called H13 and, of course, with any Geissele upper receiver, is Nanoweapon coated for maximum wear resistance and minimal corrosion.

The Reliability Enhanced BCG from Geissele comes with a Stressproof Bolt forged from bar stock Mil-Spec Carpenter 158® steel not machined, giving the bolt more than five times the life span of a traditional bolt.

If you want to build your AR-15 with all the benefits of modern technologies and advancements to have a next-generation AR-15 that will give you unparalleled reliability and superb accuracy, the Geissele Automatics Complete Upper is a clear choice.
