Description
The AWC Amphibian S Ruger KMKIII S .22LR is a specialized, integrally suppressed pistol built for ultimate sound reduction. It transforms a standard Ruger Mark III into a dedicated, whisper-quiet plinking and small-game hunting tool. This isn’t a screw-on accessory; it’s a complete, factory-integrated system where the suppressor is the barrel itself, offering permanent, reliable performance without the hassle of separate mounts. At $1353.31, it represents a significant but calculated investment for the serious .22LR enthusiast who values stealth and simplicity over a collection of interchangeable parts.
Key Features

- Subsonic Optimized: Designed to work best with standard or subsonic .22LR ammunition, making it hearing-safe.

Here’s the thing—this isn’t a budget can. The price reflects a niche product from a reputable suppressor manufacturer (AWC) and includes the host pistol. You’re paying for a turn-key, professionally assembled system. The total package weight comes in around 45 ounces, which is hefty for a .22 pistol but contributes to its stable feel and reduced recoil. It uses standard Ruger Mark III magazines, so sourcing affordable spares is easy. Remember, FFL transfer required for firearm purchases, and this item involves a NFA tax stamp process due to the integrated suppressor.
Who This Pistol Is For
This is for the shooter who has a specific, recurring need for extreme quiet. Think backyard pest control without alarming the neighborhood, or intensive small-game hunting where stealth is paramount. It’s for the person who doesn’t want to buy a pistol, then a separate suppressor, then a mounting system, and then worry about alignment. You want one tool that does one job perfectly. It’s also for collectors of unique NFA items who appreciate the engineering of an integral system. If you just want to try suppression occasionally, a threaded pistol and a separate .22 can is a more versatile, budget-friendly route.
Practical Pros & Cons
Pros: Unmatched convenience as a complete system. Arguably better sound reduction than many screw-on cans due to optimized internal volume. Exceptional accuracy potential from a fixed, rigid barrel. Drop-in ready performance—no tuning or gunsmithing needed. Built on the ultra-reliable Ruger MKIII action.
Cons: High upfront cost. It’s a dedicated tool; you can’t easily move the suppressor to another host. The length and weight make it holster-unfriendly. Requires the NFA tax stamp wait and paperwork. Not the choice for someone wanting one suppressor for multiple .22 hosts.
Frequently Asked Questions
Q: Is the suppressor removable for cleaning?
A: No. The AWC Amphibian S is a sealed, integral unit. It is constructed from durable, corrosion-resistant materials like stainless steel and aluminum to handle the corrosive salts in .22LR ammo, and is designed for long service life without user disassembly.
Q: What ammunition does it work best with?
A: It is optimized for standard velocity or subsonic .22LR rounds. High-velocity ammo may still break the sound barrier (creating a sonic crack), defeating the purpose. Stick with 40-grain rounds rated under 1100 fps for the quietest results.
Q: Can I use my existing Ruger Mark III?
A: No. The Amphibian S is a complete firearm from AWC, not a conversion kit. They use a Ruger Mark III as the base host, but the serialized receiver is permanently married to the integrated suppressor assembly. You cannot retrofit your own pistol.
When you weigh the cost against the hassle of a multi-part system, the Amphibian S makes a compelling case for the dedicated user. It’s a premium tool for a premium result.
