The Geissele Super Duty MOD1 Rifle is designed for AR-15 enthusiasts who demand excellence. Its 14.5" barrel delivers military-inspired handling while staying legal with a pin-and-welded design. Whether you're competing, defending, or just turning heads at the range, this rifle is a statement of precision, craftsmanship, and unmatched performance. Owning a Geissele isn’t just about having a rifle—it’s about having the rifle others wish they had.
Many AR-15 rifles struggle to balance durability, maneuverability, and precision. Short barrels can lack stability, while longer ones compromise handling. Add to this a sea of mediocre components, and finding a rifle that truly delivers feels like settling.
You’ve experienced it—rifles that don’t perform under pressure, or designs that scream "generic" instead of standing out. Whether it's at the range or during a competition, you want a rifle that not only performs flawlessly but also earns respect the moment it’s seen.
The Geissele Super Duty MOD1 Rifle redefines what’s possible. Its 14.5" barrel mirrors the handling of an M4A1 while integrating a mid-length gas system for smoother performance. The nanocoated BCG and braided wire spring ensure lasting reliability, while the Geissele trigger delivers the kind of precision competitive shooters dream of. With a Super Modular Rail that sets the standard for rigidity, this rifle isn’t just an upgrade—it’s an evolution.

THIS IS A SERIALIZED FIREARM. It must ship to a Federal Firearms License holder. No civilian exceptions.
Buying and shipping through Charlie’s is easy, but there is some information you need to know. Only a federally licensed firearms dealer may receive a firearm or federally regulated serialized item (like a receiver or suppressor). We cannot ship these items directly to you. Please follow these steps to process your transaction:
1) Check your state laws to make sure the federally regulated item you want to purchase is legal in your state. Your FFL dealer should be able to give you all of the necessary information regarding your state specific laws. But, if we ship to your FFL, and there is a legal issue, we cannot accept a return. So please make sure that you know and follow your local and state laws.
2) A quick google search will show you what Federal Firearms Licensed (FFL) dealers are in your area. When you are ready to purchase, contact the FFL dealer you would like to use and get their shipping address. During the check-out, put YOUR address in the “billing” section and the FFL DEALER’S address in the “shipping” section. If you don’t know your FFLs address, that’s okay. You can send the information later.
3) After check out, make sure to contact your FFL dealer to ensure they will receive your shipment for you (most do this for a small fee, but you should always double check).
4) Have your dealer send us a copy of their FFL to FFL@CharliesCustomClones.com. Charlie’s does not reach to your FFL (MAKE THEM EARN THEIR FEE!!!)
5) Be patient! In order to ensure we remain compliant with all federal laws, our compliance department is kept separate from our sales and operations team. Please allow a few days for our compliance officer to verify all of your dealer’s documents and ensure all federal laws are being observed. You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.
That’s it! We try to make this process as simple as possible for our customers, but if you are unfamiliar the process or have any other questions, please visit our How to Buy a Firearm page for more details.
