Description
If you own an Omega 36M or Hybrid 46M and want to put it to work on a pistol, this is the part that makes it happen. The SilencerCo Charlie Piston Mount is the dedicated piston housing for these modular cans, built to hold a Nielsen device so your suppressor can cycle reliably on handguns with tilting barrels. Without a booster assembly, most semi-auto pistols simply won't run right with the extra weight of a can hanging off the barrel. This mount solves that problem and keeps everything locked up tight and concentric.
What the Charlie Piston Mount Comes With
In the package you get the piston housing, booster spring, piston retainer cap, and coupler ring. One thing worth knowing before you order: the piston itself is sold separately. That is by design, since SilencerCo offers pistons in a range of thread pitches to match different barrels, whether you are running a 1/2×28 on a 9mm or something metric on an imported pistol. Grab the pitch that matches your threaded barrel and you are set.
More Than Just a Pistol Mount
Here is the part a lot of folks miss. The Charlie Piston Mount pulls double duty. With the spring and piston removed, SilencerCo's 3-lug mount threads right into the housing, which means this piece is required if you want to run a 3-lug quick-detach setup on your Omega 36M or Hybrid 46M. So even if pistols are not your main plan, this mount opens the door to fast attach and detach on subguns and pistol caliber carbines with 3-lug muzzle devices.
Built Like the Rest of the Modular Lineup
Steel construction with a black finish means this mount holds up to heat, carbon, and repeated on-and-off cycles at the range. It is a compact, no-nonsense piece that turns two of SilencerCo's most versatile suppressors into true do-it-all cans, from rifles to pistols to 3-lug hosts, all with one silencer in the safe.

Frequently Asked Questions
Does the Charlie Piston Mount come with a piston?
No, the piston is sold separately. SilencerCo offers pistons in multiple thread pitches so you can match the mount to your specific threaded barrel, like 1/2×28 for most 9mm pistols or 0.578×28 for .45 ACP. Just pick up the piston that matches your barrel threads and you are good to go.
Which suppressors does the SilencerCo Charlie Piston Mount work with?
This mount is designed specifically for the SilencerCo Omega 36M and Hybrid 46M. It is not a universal piston housing, so if you are running a different can, check that model's mounting system before ordering.
Do I need this mount to use a 3-lug mount on my Omega 36M?
Yes. With the spring and piston removed, the SilencerCo 3-lug mount threads into the Charlie Piston Mount housing. It is the required interface for running a 3-lug quick-detach setup on both the Omega 36M and Hybrid 46M.
Why do I need a piston mount to run a suppressor on a pistol?
Most semi-auto pistols use a tilting barrel design, and the added weight of a suppressor can keep the action from cycling properly. A piston mount houses a Nielsen device, which uses a spring-loaded booster to help the barrel unlock and cycle reliably. Fixed-barrel hosts like most rifles and carbines do not need one.
