The Geissele Super Duty® Upper (Stripped) features the quality and workmanship you’ve come to expect from the Geissele name. This 10.3″ upper receiver in 5.56MM is finished in DDC (Desert Dirt Color) and delivers a precision-engineered platform for custom builds. It features an in-house Manganese Phosphate coated, CHF, Chrome Lined barrel with a 1-7 twist rate, precision machined and cold hammer forged at the state of the art facility in North Wales, PA using the highest quality materials available.
The Super Duty upper receiver mates to a MK16 Super Modular rail via a center aligning tab, removing any chance of rail rotation, and this family of rails is renowned by operators for their performance and comfort. The 9.3″ MK16 rail features Geissele’s Center Tab design. The precisely balanced gas system includes the bomb-proofed Super Compact Gas Block with fine-tuned gas port sizing, minimizing felt recoil while maintaining reliable cycling, even in adverse conditions. The carbine length gas system and .070″ gas port size work seamlessly with the 1-7 twist to handle a versatile range of 5.56 NATO ammunition weights.
This is a stripped upper receiver—the BCG and Charging Handle are not included—allowing you full customization of your build. Complete specifications include a weight of 2 lbs 10 oz and the Super Duty Receiver platform. Whether building a precision rifle or a compact tactical system, the Geissele Super Duty Stripped Upper delivers the durability and accuracy serious shooters demand.
