The MS‑57K by Maxim Defense is a high-performance, short-length suppressor built specifically for firearms chambered in 5.7x28mm. Designed for superior gas management, durability, and modularity, it features M‑Kore™ internal technology that reduces blowback and sound signature during suppressed fire—even in full-auto environments.
This suppressor is constructed with a 17‑4 stainless steel core, Grade 5 titanium mount and thread insert, and a 7075‑T6 aluminum tube. The MS‑57K measures just 4.4 inches in length (with mount), maintains a 1.5″ outer diameter, and weighs only 6.6 ounces, making it ideal for compact weapons, pistols, or PDW-style platforms.
The suppressor includes two direct-thread mounts—½×28 and M10×1—for compatibility across multiple host weapons. Integrated carbon cutters help reduce internal fouling, making the MS‑57K user-serviceable with basic tools. Its robust construction and advanced internals ensure reliable, low-blowback operation even under demanding conditions.
