FX Wildcat MKIII Compact


The FX Wildcat MKIII 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.

Note: Item includes a DonnyFL 5″ Moderator.
