The mp22s (mostly printed 22 silencer) is the most advanced rimfire silencer ever made, and has no equal in either the Form 1 or Form 4 spaces. That's a bolt statement, but hear me out. Utilizing a sealed monocore that works in conjunction with a carbon fiber sleeve, it is easily and cheaply serviced with zero mess. Tensegrity is achieved by its unique "keystone ring," which provides primary structural integrity to the system, both placing the components under tension and compression, and also reinforcing the threads like a barrel band. The flexible walls of the tensioned monocore impart outward force on the compressed carbon fiber sleeve, which is then redirected back to the keystone ring, pushing it rearwards, thereby reinforcing the threaded structures directly under it. In this way, the keystone ring keeps the entire system locked in place (hence the analogy to the keystone in an arch). Since the walls of the monocore are flexible and contained by the compressed sleeve (the compression provided by the keystone ring), which has a very high modulus, the coefficient of friction between the monocore and sleeve prevents layer separation, meaning it's not necessary to glue the monocore in place, resulting in easy maintenance.
The primary advantage of the mp22s is the extremely tight bore, which would be impossible with an Form 4 silencer, as well as most Form 1 silencers due their difficult to service nature, being that they require glue to achieve structural integrity. Whereas with those silencers there is considerable risk associated with a tight bore, the mp22s is so cheap and easy to service there is no risk. Most baffle strikes require no remediation, and in the case of a catastrophic strike all you've lost is fifty cents of plastic. The monocore is fast and cheap to replace in the event of a baffle strike, and the primary structural component (the keystone ring) is placed in a such a way that it cannot be damaged or lost, even in the event of a tube strike or launch, meaning this tax stamp is for life (and the lives of your children and their children and their children and...moral of the story is the serialized component is immortal). The mp22s has a bore of 6mm, vs. the typical 7mm, resulting in significantly increased performance.
The second advantage is that the monocore, being completely sealed, is so cheap and easy to replace that cleaning is no longer necessary. Instead of cleaning the core, simply discard and replace it. All the fouling is contained inside of it, so you won't get your hands dirty or have to clean the other components. Other glue-in designs require significant work and expense to service, whereas the mp22s can be recored for about fifty cents in well under a minute, usually without tools (if the keystone is tight, the included wrench can be used).
The easily serviced design also makes upgrades easy. Since the mp22s is open source, it's expected that improvements will be made by the community at large. Improvements in materials and printers will also undoubtedly increase the viability and longevity of the monocores in the future; it's not unthinkable that the home FDM printer will soon be capable of producing monocores that will rival any factory can for durability for this application, given the low demands of 22lr.
There seems to be an inherent advantage with FDM for sound suppression, which I attribute to the dampening properties of the plastic in part, but mainly I believe that the semi-permeable nature of FDM prints helps to reduce first round pop. I can't perceive any first round pop, which I hypothesize probably comes from the fact that the permeability of the chambers isn't allowing the pressure in the blast chamber to spike high enough to combust the oxygen, resulting in wet performance without the need for actual ablative (which is messy and annoying).
At 46g (1.6oz) it's also one of if not the lightest silencers in its class. Typically, a silencer of this size will be in excess of 6oz. This results in very minimal impact to your barrel's harmonics, which means minimal shift in point of impact and shot spread.
Last but certainly not least, the aesthetics are top notch. It looks great, and there are LOTS of options to make it your own. There are different carbon fiber patterns and finishes, multitudes of color options for filament, and the aluminum ring can be anodized or cerakoted in many different colors. The aluminum can be substituted with titanium for even more styling options, like rainbow anodizing.
If you want to support this project, please consider buying the TDP from my website: https://jackbanksdesign.com/product/mp22s-technical-data-package/
Your support will enable further development. I'm not an SOT, so it's 200 dollars a pop for me to experiment, and I would like to develop variants of this design for other calibers, as well as send this one off for testing.
