FX Wildcat MK3 BT — Power and Caliber Specifications

The Wildcat MK3 BT delivers exceptional performance across four calibers. The FX Wildcat MK3 Compact energy reaches up to 70 joules in .22, 85 joules in .25, and 126 joules in .30 caliber. Magazine capacities are caliber-specific: 18 shots in .22, 16 shots in .25, and 13 shots in .30 caliber. The 300cc carbon fiber bottle fills to 250 bar and provides approximately 110 shots in .22, 70 shots in .25, and 35 shots in .30 caliber per fill. The 500mm Superior STX barrel features a ½ inch UNF threaded muzzle for moderator attachment. The rifle weighs 3.0 kg, and overall length measures 670mm.

BT Bottle Version and Shot Capacity

The “BT” designation stands for Bottle, and it’s the real game-changer here. FX swapped the traditional under-barrel tube for a 300cc carbon fiber bottle, dramatically increasing shot count. This eliminates “air anxiety” and lets you stay focused on your reticle instead of your tank levels. The Wildcat MKIII BT Compact delivers a significantly higher shot string than almost any other bullpup in this size class. The carbon fiber bottle is removable and fills to 250 bar through the Quick charge system MkII.

89cc Power Plenum and Dual AMP Regulators

The massive 89cc Power Plenum sets the BT version apart from standard Wildcats. This large plenum caters towards slugs and heavy pellets, effectively extending both muzzle energy and range. Taming this power center uses dual FX AMP Regulators. The first regulator reduces the initial pressure from the carbon bottle. The second regulator provides the precise amount of air needed for consistency with each shot. Both regulators are externally adjustable for fine-tuning. Combined with the Superior STX barrel system, this ensures you have the most accurate rifle possible.

Rear Power Adjuster and Tuning Capability

Complete adjustability is in your hands with the Wildcat MkIII BT. The rear power adjuster features seven preset positions for the hammer spring. In the eighth position, a small hole opens up for micro-adjustments with an Allen key. This allows you to shift from higher speeds for long outdoor shots to dialing down the power for barn or backyard shooting. The Wildcat’s two-stage match trigger is smooth with a super clean break. The side lever is silky smooth and positioned perfectly above the trigger for lightning-fast follow-up shots.

FX Wildcat MK3 — Real-World Accuracy and Performance

Owners consistently praise the Wildcat’s accuracy and reliability. One reviewer achieved ½-inch groups at 50 yards and 2-inch groups at 100 yards. A Krale customer reported 15mm groups at 25 meters after fitting a carbon fiber sleeve. Another user achieved 1cm groups at 30 meters with JSB Hades pellets for rat control. The rifle is accurate and tunable enough to perform in 100-yard benchrest matches in the right hands. The Side-Shot magazine has been redesigned with stronger materials and an optimized internal mechanism that rotates smoothly even with heavy slugs.
