The CAT Johnny Law is a precision-rifle suppressor built by engineers who weren't willing to settle for off-the-shelf solutions. The entire can is additive-manufactured from 6Al4V titanium, which lets CAT build internal geometries that simply aren't possible with conventional machining or welded construction. The result is a lightweight, aerospace-grade .308-class suppressor optimized for long-barrel precision work — CAT's stated sweet spot is a 20" .308 platform, with the M110A2 as the reference build.
Highlights: purpose-built for precision rifle platforms, full additive-manufactured 6Al4V titanium construction, CAT Spooky QD mount with anti-seize design, sacrificial "waffle" erosion interface at the blast chamber, Diamond-Like Carbon (DLC) finish, and CAT's SNIPER2 technology throughout.
The Spooky mounting system runs left-hand threads on the suppressor against right-hand threads on the muzzle device — so if the can ever gets stuck and needs a wrench, the muzzle device stays on the barrel instead of getting trapped inside the suppressor. Smart design, field-proven logic. CAT rates the Johnny Law up to .300 Win Mag and .300 PRC with barrels above 22"; .300 RUM and .300 Norma are not rated. Pew Science lab-tested the JL on a 20" .308 — see the sound signature data here.

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.
