More Power. More air.

The Wildcat expands again! From the original iconic bullpup, to the new 2022 model that’s infused with power & more air! Meet 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 all their various shapes and sizes. The form and function of this epic airgun has made it the favorite off-hand hunting PCP for the last 7 years.

89cc Power Plenum

The enhanced power comes courtesy of the massive 89cc Power Plenum, nestled in the stock of the Wildcat. This large plenum really 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. (Those preferring classic-sized pellets are better served by the standard Wildcat MKIII).

Dual FX AMP Regulators + Smooth Twist X Barrel

Taming this massive power centre 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. This provides less stress as well as allows 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!

Supreme adjustability

Complete adjustability is in your hands with the Wildcat Mk3 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 for target practice in the backyard. This rear power adjuster also allows quick micro and macro adjustments to fine-tune the desired speed for the projectile you are shooting.

FX Wildcat owners also have the option of using the FX Wildcat Slug Power Kit (sold separately) which allows for even more power and velocities to tailor to heavier projectiles.

The original iconic Wildcat completely changed the airgun world, offering the perfect offhand 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.

Wildcat MKIII Standard (released may 2020)

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 enhances its legacy as it updates this desired platform for the modern airgunner. The improvements start inside the Wildcat’s main block. FX has increased the plenum size and air flow of the rifle while also increasing the valving of the Wildcat. The engineering into the new Wildcat block really pushes the boundaries of what can be accomplished with precision CNC engineering.

Adjustments to the Wildcat MKIII are built around the new rear power adjuster.  This power adjuster is a breakthrough as it allows for both micro and macro adjustments using the same dial to the hammer spring. The rear power adjuster has 7 presets for your hammer, but the actual hammer tension can be adjusted more fully higher or lower using an Allen wrench through a hole found on the 8th position of the adjuster. This allows the Wildcat hammer to be fully adjusted in harmony with the AMP regulator to allow for the full range of adjustability found in other FX rifles like the FX Impact & FX Crown. This also allows for shooters to swap calibers quickly and easily (additional barrel kits will be available).

The Wildcat MKIII has also upgraded its magazine to allow the use of larger capacity magazines. No longer restrained to 8 shots, the Wildcat MKIII now more than doubles its shots using the FX Side-Shot magazine (the same magazines as found on the FX Crown and FX Dreamline). All Wildcat MKIII will ship with Superior STX Barrel Liners. The liners are housed in the STX Interchangeable barrel liner system that allows users to switch to the Superior STX Heavy liner if they want to shoot heavier slugs. The other features of the Wildcat remain intact. The externally adjustable AMP regulator, two stage adjustable trigger (easily one of the best triggers found on any bullpup), and the smooth side cocking lever perfectly positioned above the trigger.
