Manufacturer by Geissele Automatics in the USA, and brought to you by Charlie's, this 16” complete upper chambered in 5.56mm; features a DLC-coated HUXWRX Flash Hider-QD muzzle device mounted to an 16” Manganese Phosphate coated, CHF, Chrome Lined 1-7 twist barrel.
Geissele Automatics' Super Duty Mod1 Complete Upper Receiver offers discerning rifle owners a significant upgrade over previous Super Duty models. Incorporating a reinforced Quik-Detach (QD) sling swivel grommet, the smooth-operating Geissele Airborne Charging Handle, and a precision-machined M-LOK handguard, this 16" 5.56mm upper receiver delivers enhanced performance, reliability, and customization options to take your shooting experience to new heights.
The Super Duty Mod 1 offers discerning rifle owners a significant upgrade, incorporating premium components for enhanced reliability and durability. The upper builds upon the company's Super Duty line, introducing several key upgrades. One important enhancement is the introduction of the HUXWRX flash hider, replacing the Geissele proprietay flash hider. Another is the reinforced Quik-Detach (QD) sling swivel grommet, a feature absent from earlier Super Duty upper receiver models.
This reinforced QD grommet provides a more secure attachment point for your sling, ensuring your rifle remains firmly in place during dynamic use. In contrast, previous Super Duty uppers relied on the sling attachment built into the handguard or stock, which was not as robust or reliable.
Crafted from high-quality materials and machined to exacting standards, this upper receiver group delivers exceptional accuracy and reliability. The 16" chrome-lined, phosphate-coated barrel provides consistent performance and durability for thousands of rounds and protection from corosion.
The Mk16 M-LOK handguard is a variant of the original URGI handguard, made by Geissele for USASOC special forces as part of the US Army's M4A1 upgrade program in 2018. The handguard enables lightweight customization to suit your specific needs. The durable black nitride finish further enhances the corrosion resistance of this upper receiver, making it well-suited for real-world use.
The Super Duty Mod1 also features Geissele's acclaimed Airborne Charging Handle, offering smoother and more controlled operation compared to standard mil-spec designs. This upgraded charging handle allows for easy and reliable manipulation, even with gloved hands, a valuable asset in tactical scenarios.
Alongside the upgraded upper receiver, this package includes Geissele's meticulously engineered Reliability Enhanced Bolt Carrier Group.
The Reliability Enhanced Bolt Carrier Group features a chrome-lined gas key that has been properly torqued and staked for consistent performance. Crafted from advanced H13 steel and coated with Geissele's Nanoweapon finish, the cam pin delivers superior corrosion and wear resistance. The extended upper rails on the carrier group provide greater stability, dramatically improving feeding reliability.
At the heart of the Reliability Enhanced Bolt Carrier Group is the Geissele Stressproof Bolt, developed in collaboration with Carpenter Steel metallurgists. Forged rather than machined from bar stock, the Stressproof Bolt is made from Carpenter 158+ material, which is cleaner and contains fewer impurities. This results in a stronger, more fatigue-resistant bolt capable of lasting up to five times longer than a standard mil-spec design. Each Stressproof Bolt undergoes rigorous inspection, high-pressure testing, and magnetic particle inspection before receiving Geissele's Nanoweapon coating.
Together, the enhanced upper receiver and premium bolt carrier group of the Geissele Super Duty MOD1 Complete Upper Receiver deliver a significant performance upgrade for your rifle. Discerning shooters seeking exceptional reliability, durability, and precision will find this package an excellent choice for elevating their shooting experience.
