Let's be real - when you name a suppressor "Old Dirty Bastard," it better live up to the attitude. CAT's ODB Inconel HUB doesn't just live up to it - it redefines what's possible in a duty-grade suppressor.
The CAT ODB 7.62 Suppressor features SURGE BYPASS technology and is made using Laser Powder Bed Fusion (LPBF) with internal structures designed to optimize gas flow and reduce sound.
At the heart of the ODB Inconel HUB is CAT's advanced Surge Bypass technology, engineered to manage pressure waves and gas flow with unprecedented precision. This isn't just marketing speak - it's the result of extensive computational fluid dynamics modeling and real-world testing.
The suppressor is constructed from Inconel 718, a nickel-chromium super alloy that thrives in extreme conditions. This remarkable material maintains its structural integrity at extreme temperatures that would compromise lesser materials. The 3D printed construction allows for complex internal geometries that would be impossible with traditional manufacturing methods, optimizing every cubic millimeter for performance.
CAT has designed this suppressor to excel across a wide range of loads. While it's optimized for 16" AK-47 platforms, it delivers outstanding performance on 5.56 NATO and .300 Blackout platforms as well. Its robust design handles everything from short-barreled applications to full-power battle rifles.
The 1.375x24 threaded mount (HUB) interface gives you flexibility in mounting options, while maintaining rock-solid stability under sustained fire. Unlike typical suppressors in its class, the ODB Inconel demonstrates exceptional endurance during high rates of fire. It's not just about surviving full-auto - it's about maintaining consistency and performance through extended sessions.
For those concerned about signature reduction, the Inconel 718 construction offers an additional advantage: zero titanium sparking. This makes it ideal for professional users who require maximum signature control in all conditions.
Pew Science has tested the ODB on both the ubiquitous Mk18 and a bolt action .300 Blackout.

1) Check your state laws to make sure the federally regulated item you want to purchase is legal in your state.
2) Find your FFL… Have your dealer send us a copy of their FFL and SOT to Charlie’s (Make them earn their fee!). Not every FFL is a SOT or Class 2 / Class 3 dealer.
3) Be patient! 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. Please click the “Buying a Firearm” tab at the top of this page for more information.
THIS IS A SERIALIZED ITEM. 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 Suppressor page for more details.
