Precision Engineering Meets Tactical Versatility in ODG

The Geissele Super Duty Mod 1 Upper Receiver Group in OD Green represents the latest evolution in Geissele's commitment to designing and building superior upper receiver groups. 

Key Features of the Mod 1 Upgrade:

- HUXWRX 556 DLC Nanocoated Flash Hider
- Steel-reinforced QD sling attachment points
- Enhanced compatibility with next-generation suppressors

Unique OD Green Finish:  The OD Green anodized finish is unique to Geissele, and showcases craftsmanship and the challenges of precision manufacturing. This finish is known for its wide variation, ranging from dull gray-green to forest green, and even the distinctive "40mm ammo can green" seen in other Geissele products. Due to these variations and limited production runs, OD Green Geissele products are becoming increasingly rare, adding to their collectible value.  But, with that also comes the expectation that the color you see in the pics might not be the exact color you receive.

Core Components:

1. Upper Receiver: Precision-machined OD Green upper with a unique dovetail cut-out, designed specifically for the Geissele Mk16 rail system.

2. Barrel: 10.3" Geissele barrel, cold hammer-forged and chrome-lined with a 1:7 twist rate. The Black Oxide coating adds durability and corrosion resistance.

3. Handguard: 9.3" Super Modular Rail (SMR) MK16, a variant of the 13.5" version used by USASOC. The rail's dovetail interface with the upper receiver ensures rock-solid alignment and stability.

4. Gas System: Carbine-length gas system with Geissele's "bombproof" low-profile gas block, secured with both set screws and a through-barrel pin for unparalleled reliability.

5. Bolt Carrier Group: Geissele Reliability Enhanced BCG (REBCG) featuring:
- DLC Nanocoating for improved lubricity and wear resistance
- Extended upper rails for enhanced stability and feeding reliability
- Carpenter 158+ Stressproof Bolt, forged for optimized grain structure
- H13 tool steel cam pin for superior durability

6. Charging Handle: Geissele Airborne Charging Handle (ACH) for smooth, reliable operation in all conditions.

7. Muzzle Device: HUXWRX 556 DLC Nanocoated Flash Hider, optimized for suppressor compatibility and superior flash reduction.


Performance and Versatility:  This upper receiver group is ideal for close-quarters battle (CQB) scenarios, offering a perfect balance of maneuverability and firepower. The 10.3" barrel length provides excellent handling in tight spaces while maintaining effective ballistics for close to medium-range engagements.

The integration of the HUXWRX flash hider enhances the upper's versatility, especially for users planning to run suppressed. This upgrade puts the Mod 1 on par with earlier versions that featured the sought-after Surefire SOCOM flash hider.

Geissele's Attention to Detail:  True to their reputation for over-engineering, Geissele has implemented features that go above and beyond standard specifications. The bombproof gas block installation and the dovetail rail interface are prime examples of Geissele's commitment to reliability and precision.  Nanocoating is another, which is DLC coating applied to both the bolt carrier group and the flash hider for superior performance and corrosion resistance.

The Geissele Super Duty Mod 1 Upper Receiver Group in OD Green is a premium choice for discerning shooters who demand the utmost in quality, reliability, and performance. Whether for professional use, home defense, or tactical competitions, this upper delivers exceptional results in a compact, battle-ready package.
