FX Leopard Compact Tube

Compact Bullpup. Over-Barrel Air System. AMP MKII Regulator. 

The FX Leopard Compact Tube is a precision-engineered bullpup designed for hunters and all-around shooters who demand a lightweight, maneuverable platform without sacrificing performance. Built around a 210cc over-barrel air reservoir with 54cc power plenum, AMP MKII externally adjustable regulator, Quick Tune system, STX Superior barrel liner optimized for pellets and slugs, and a 20 MOA Picatinny rail — all in a compact 690mm (27.2″) package at just 7.5 lbs.

The Leopard Compact Tube’s over-barrel air system creates a streamlined, well-balanced bullpup profile with excellent ergonomics for field carry and off-hand shooting. The 54cc power plenum delivers consistent regulated airflow, and the AMP MKII externally adjustable regulator combined with the Quick Tune system provides precise control over hammer spring tension and airflow for fine-tuned velocity performance without disassembly. The STX Superior liner handles both pellets and slugs accurately, and the tool-less adjustable butt pad with two-stage adjustable trigger and AR-compatible UG1 grip delivers a fully customizable ergonomic fit.
