FX Airgun’s Premier Bullpup Air Rifle

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.

Adjustments to the Wildcat MKIII are within the new Advanced Rear Hammer Dial or ARH dial for short. This hammer adjuster is a breakthrough as it allows micro and macro adjustments using the same dial. The ARH Dial has seven presets for your hammer, but the actual hammer tension can be adjusted fully up or down using an Allen wrench through a hole found on the 8th position of the adjuster. Ease of adjustments allows the Wildcat hammer to be fully adjusted to match any caliber you wish to shoot (additional barrel kits will be available).

The Wildcat MKIII has also upgraded its magazine to allow larger capacity magazines. No longer restrained to 8 shots, the Wildcat MKIII now more than double the shots using the FX Side-Shot magazine (the same magazines as found on the FX Crown and FX Dreamline).

All Wildcat MKIIIs will ship with FX’s new Superior STX Barrel Liners. The liners in the STX Interchangeable barrel liner system will allow users to switch to the Superior STX Heavy liners to shoot heavier projectiles like Slugs.
Outside of the Picatinny scope rail that is now standard on all Wildcats, 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 is positioned perfectly above the trigger.

The Wildcat MKIII comes in two configurations, The Wildcat MKIII Compact with its 500mm barrel in calibers .177 thru .30; and the Wildcat MKIII Sniper that houses a larger 300cc air cylinder and a 700mm barrel in calibers .22, .25 & .30. All rifles are available in a synthetic stock with shrouded barrels that are moderator ready with ½” UNF threading (Moderator sold separately).
