DonnyFL RONIN .357 "Big Bore" Moderator

Compact. Lightweight. Big Bore Ready.

The DonnyFL Ronin .357 is a redesigned, more compact alternative to the Emperor — delivering serious big bore sound suppression in a shorter, lighter package without sacrificing performance. Featuring a redesigned rear cap for reduced weight, a mono-core design for enhanced accuracy, and tool-free maintenance in under 10 seconds, the Ronin .357 is the go-to moderator for serious .357 caliber airgunners who want performance and practicality in equal measure.

Overview

The Ronin .357 builds on the original 1/2x20 Ronin platform with a purpose-built big bore configuration featuring M18x1 threaded end cap for direct compatibility with .357 caliber airgun platforms. The mono-core design eliminates the pellet clipping risk associated with multi-baffle designs, and with no moving parts or epoxy to loosen over time, this moderator is built to deliver consistent performance for the long haul. Sandblasted and anodized for maximum durability, and pre-wrapped in felt for a refined finish.

Key Features

  • Compact big bore moderator — shorter and lighter than the Emperor
  • Designed specifically for .357 caliber airguns
  • M18x1 threaded end cap for direct big bore platform compatibility
  • Mono-core design enhances accuracy and minimizes pellet clipping risk
  • No moving parts or epoxy — nothing to loosen over time
  • Tool-free disassembly in under 10 seconds — unscrew the rear cap
  • Pre-wrapped in felt for a clean, refined finish
  • Machined exterior grooves for improved grip during handling
  • Sandblasted and anodized finish for maximum durability
  • Precision CNC-machined by professional machinists
  • Redesigned rear cap reduces overall weight
  • 2" x 6.25" dimensions
  • 9.7 oz

Performance Advantage

  • Mono-core design delivers consistent, accurate suppression without the pellet clipping risk of multi-baffle alternatives
  • Compact 6.25" length provides meaningful sound reduction without excessive added length
  • No moving parts or epoxy means reliable, consistent performance over years of hard use
  • Tool-free maintenance keeps your Ronin clean and serviced in under 10 seconds
  • Machined grip grooves ensure confident handling during installation and removal
  • Lighter than the Emperor while maintaining serious big bore suppression capability
