The FX Wildcat is a part of airgun royalty. A rifle that was compact before compact became a buzzword in airguns, a perfectly balanced and ergonomically designed bullpup that defined the generation of bullpups that have followed in its footsteps.
The FX Wildcat MKIII perfects its legacy as it updates this coveted platform for the modern airgunner. The enhancements start inside the Wildcat’s block. FX has increased the plenum size and airflow while also increasing the valving of the Wildcat. The engineering into the new Wildcat block pushes the boundaries of what we can achieve with precision CNC engineering from FX Airguns.

The Original Iconic Bullpup Infused with Power & More Air!

Introducing the new and vastly improved FX Wildcat MkIII BT! The iconic airgun bullpup, the FX Wildcat, now comes with power and air capacity to handle slugs and heavier pellets in various shapes and sizes. The form and function of this epic airgun have made it the favorite off-hand hunting PCP over the last seven years. The enhanced power comes courtesy of the massive 89cc Power Plenum, nestled in the stock of the Wildcat. This large plenum caters to slug and heavy pellets. Effectively extending both the muzzle energy and thus the range in which you can use this new and powerful Wildcat. (The standard Wildcat MKIII better serves those preferring classic-sized pellets). Taming this massive power center and refining accuracy is accomplished using dual FX AMP Regulators.

The first AMP regulator is placed just after the carbon fiber bottle (aluminum bottle on the lower-priced VP version) to reduce the initial pressure in preparation for the second regulator. Dual aMP regulators provide less stress and allow the use of 300 BAR bottles. The second AMP regulator allows the precise amount of air needed for consistency with each shot. Combined with the world’s most competition-winning barrel system (the FX Smooth Twist X Barrel System), this ensures you have the most accurate rifle possible in your hands!

Complete adjustability is in your hands with the Wildcat MkIII BT! Both regulators are externally adjustable, and the rear power adjuster makes dialing in the right power easy to adjust for shifting hunting situations. A shooter can shift from the higher speeds needed for a long outdoor shot to dialing down the power for a shot taken in a barn or target practice in the backyard. This rear power adjuster allows quick micro and macro adjustments to fine-tune the desired speed for your shooting projectile. The FX Wildcat MkIII BT comes in three configurations: The Compact with a 300cc carbon fiber bottle and 500mm barrel, The Sniper with a 580cc carbon fiber bottle and 700mm barrel, and the value-priced VP with a 400cc aluminum bottle and 600mm barrel. Additional barrel kits in calibers .177 thru .30 are sold separately and are easily interchangeable. FX Wildcat owners also can use the FX Wildcat Slug Power Kit (sold separately) that allows for even more power and velocities to tailor to heavier projectiles.

The original iconic Wildcat completely changed the airgun world, offering the perfect off-hand shooting air rifle. The Wildcat MkIII BT perfectly matches the advances to slugs and heavier pellets the modern shooter desires, ushering in a new generation to the brilliance of the FX Wildcat.
