Product Info for Geissele 5.56mm Super Duty MOD 1 Upper Reciever

At Geissele Automatics, we constantly challenge ourselves by pushing the boundaries of quality and performance. Based on our Super Duty platform, our Super HBAR Uppers feature a thicker HBAR profile, with significantly thicker Super HBAR straight gas tube. Our Super HBAR Upper effortlessly handles higher volumes of fire without sacrificing match grade accuracy.image

Foundational to the renowned quality and performance of this system is the in-house produced Cold Hammer Forged, chrome-lined Super Heavy Barrel and Nanoweapon-coated Reliability Enhanced Bolt Carrier Group. Both the Geissele CHF barrel and Forged Stressproof Bolt® are High-Pressure Tested (HPT) and Magnetic Particle Inspected (MPI), and work in concert to achieve unmatched dependability with match-grade accuracy.
