FX Wildcat MKIII BT Compact Airgun

Years of Favorites. Now More Powerful. Built for Slugs.

The FX Wildcat MKIII BT Compact is the new and improved evolution of one of the most beloved off-hand hunting PCPs ever made — now with more power and air capacity to handle slugs and heavier pellets than ever before. The massive 89cc Power Plenum, Dual FX AMP Regulator System, and Superior Smooth Twist X barrel combine to deliver a compact, lightweight, exceptionally accurate platform that extends effective hunting range while remaining one of the most manageable field rifles FX has ever produced.

Overview

The Wildcat MKIII BT's 89cc Power Plenum is the heart of its performance upgrade — purpose-built for slugs and heavy pellets, it effectively extends muzzle energy and practical hunting range beyond what the standard Wildcat MKIII can achieve. The Dual AMP Regulator System tames that power with precision — the first regulator reduces initial pressure from the 300cc carbon fiber bottle, and the second delivers an extremely precise, consistent air charge to every shot. Combined with the externally adjustable regulators and rear power adjuster for macro and micro tuning, the MKIII BT gives you more control over your rifle's performance than any previous Wildcat.
