Knights Armament (KAC)
The Knight's Armament KAC Mk11 7.62 NATO suppressor — the program-correct can for the KAC SR-25 Mk11 Mod 0 and the Mk13 Mod 5 sniper systems.
The Mk11 suppressor is a purpose-built component of the Knight's Armament Mk11 Mod 0 sniper system, adopted by Naval Special Warfare in the late 1990s and early 2000s. It is not a universal 7.62 can — it is designed to mate exclusively with the Mk11 Mod 0 and the Mk13 Mod 5 barrel and gas block configurations, using a gate-latch QD interface that indexes to a 6 o'clock timing pin on the gas block. Attempting to mount this suppressor on a rifle without the correct barrel and gas block specifications will result in a dangerous misalignment.
This is an important distinction for clone builders: the Mk11 suppressor and the M110 SASS suppressor are different parts from different programs. The M110 SASS (fielded circa 2008) uses a later-generation KAC suppressor with a different mount, different finish, and different barrel interface. The two are not interchangeable on a clone-correct build. The Mk11 suppressor belongs on the Mk11 Mod 0 — the earlier NSW sniper system built on KAC's SR-25 platform with a 20" match barrel, KAC free-float rail, and Leupold Mark 4 LR/T 3.5-10x40 M3 optic.
We stock these when KAC makes them available. If you're building a Mk11 Mod 0 clone, this is the suppressor — there is no substitute. We've got your six on the clone-correct details.
This item is a suppressor and must ship to an FFL/SOT holder. No civilian exceptions.
1) Check your state laws to confirm the item is legal in your state.
2) Find your FFL/SOT dealer and have them send a copy of their FFL and SOT to Charlie's. 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, reach out for a status update.

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.
