Few rifles have captured modern military history enthusiasts’ attention like the M110 Semi-Automatic Sniper System (SASS). Introduced by Knights Armament during a period where semi-auto precision rifles were becoming indispensable, the M110 gave snipers and designated marksmen a new edge in speed and sustained accuracy. Central to its signature silhouette and reduced muzzle report was the M110 suppressor. However, because Knights Armament has discontinued manufacturing this specific can, collectors, shooters, and military historians have been left searching for an alternative to complete their exact M110 build. That’s where this Potomac Armory M110 SASS Suppressor (Replica) steps in.
A clone product, by definition, seeks to recreate the look and fitment of the original item. Clone builders want that authentic design—correct length, diameter, and attachment interface—so their rifles precisely mirror the U.S. military’s legendary firearms. For anyone currently piecing together a faithful M110 build, this suppressor replicates the form factor from the early 2000s. It’s important to note that this is not a Knights Armament product; it’s designed to fit seamlessly on a KAC or Potomac Armory 20" M110 barrel. The performance similarities or differences compared to the original have not been evaluated, but it retains the correct outer profile and mounting system for those wanting the same aesthetic and handling profile.
Potomac Armory introduced this clone suppressor to address a pressing need in the firearms community. As original Knights M110 suppressors are no longer in production, your options are extremely limited if you want a period-correct version. Authentic barrels and gas blocks are also uniquely configured for this design, so it’s essential to use the correct mounting components. Whether you’re building a display rifle or a shooter-grade M110 clone, having the right suppressor completes the picture.
Potomac Armory’s lineage is steeped in the careful reproduction of military-correct parts. Known for attention to detail and historically accurate craftsmanship, Potomac Armory has long supported collectors and precision shooters who value authenticity. Their heritage lies in bridging the gap between discontinued military components and modern-day reenactors, historical collectors, and shooting enthusiasts. Each part they produce is carefully researched, with patterns taken from period items so the end user can confidently replicate the original rifle’s features.
The Potomac Armory M110 SASS Suppressor (Replica) as sold by Charlie’s Custom Clones, is a trusted source for military-accurate clone components and builds. For those who appreciate the engineering and history behind one of the U.S. military’s most iconic semi-auto sniper platforms, this suppressor fills the gap left when the original Knights Armament units were discontinued. This item lets dedicated M110 builders recreate the look of the early-2000s rifle, preserving a piece of modern sniper heritage while staying true to the rifle’s legacy and overall aesthetic.

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.
