FX - Dynamic MkII EXP Black - 500

Compact. Maneuverable. Full Dynamic Performance.

The FX Dynamic MkII EXP in 500mm is purpose-built for shooters who need a compact, highly maneuverable platform without sacrificing the advanced performance features that make the Dynamic MkII EXP exceptional. Built on the upgraded Dynamic Block system with an over-barrel Dynamic plenum and externally adjustable AMP MkII regulator, this shorter configuration delivers the increased airflow, consistency, and tunability of the full Dynamic platform in a field-friendly, agile package.

Overview

The 500mm barrel configuration prioritizes mobility and handling — making this the ideal choice for hunters, field shooters, and anyone operating in tighter environments where a longer barrel becomes a liability. Despite the compact profile, the Dynamic plenum system, upgraded Dynamic Block, and AMP MkII regulator ensure strong power output, consistent shot performance, and precise tunability that serious shooters expect. A 480cc carbon fiber bottle, Quick Set Trigger, integrated 30 MOA Picatinny rail, full-length ARCA rail, and M-LOK compatibility complete a platform that performs as well in the field as it does on the range.
