What makes FX Airguns different?
Founded in 1999 by Fredrik Axelsson in Mariestad, Sweden. Handcrafted PCP airguns built around the Smooth Twist X (STX) barrel: rifling pressed into the steel from the outside, leaving a smooth bore that shoots both pellets and slugs accurately. STX liners are interchangeable across the Impact, Crown, and Wildcat platforms, so one rifle can change caliber, length, or twist rate without buying a new gun.

Which FX Is Right for You?
Bench, target, Extreme Benchrest. Impact M3. Most adjustable rifle in the FX lineup. Tuning time required, but the ceiling is high.
Backyard pest control and walking hunting. Wildcat MkIII. Bullpup layout fits a 700mm barrel in a carbine-sized package. Easier to tune than the Impact.
Traditional sporting and small game. Crown. Wood stock, simpler to tune. Same STX barrel system as the Impact.
Slug shooting at extended range. Order in .25 or .30, add an STX kit matched to slug weight, fit the FX Tungsten Hammer for the extra hammer energy slugs need.
Caliber guide. .22 for small pests and paper. .25 for general hunting and target. .30 for larger pests and Extreme Benchrest slugs. .35 for the heaviest slugs and longest ranges.

Frequently Asked Questions
My FX Impact's first shot after sitting is slow. Is something wrong?
Known FX Impact valve behavior. The plastic valve face seats into the o-ring under regulator pressure and friction climbs over time, so the first shot needs more hammer energy. Fix: a thin film of silicone grease on the valve face, fresh o-rings, clean valve rod. Burn one or two shots on the chronograph before a hunt or match string.
Are FX STX barrel liners interchangeable between Impact, Crown, and Wildcat?
Liner architecture is shared, but housings and clamping are platform-specific. Use Impact STX kits in Impacts, Crown STX Superlight in Crowns, Wildcat MkIII Superior STX in Wildcats. Caliber and length swap within each platform.
FX pellets or Hybrid Slugs?
Pellets are easier to tune and shoot well at most factory settings. Hybrid Slugs hold velocity and fight wind better past 50 yards but reward a tuned setup. Start with pellets, move to slugs once the rifle is dialed.
Which caliber should I buy first?
.25 is the sweet spot for most buyers: enough energy for hunting, plenty of pellet and slug variety, reasonable shot count per fill. Pick .22 for small pests and paper, .30 for maximum slug performance, .35 for a long-range slug rig.
How do I fill an FX PCP?
Three options: hand pump (cheap, 500 to 1000 strokes per fill), 4500 PSI carbon fiber tank (fast, refilled at a dive or paintball shop), or a PCP-rated electric compressor (most convenient, highest upfront cost). Fill slowly. Never exceed the rifle's stamped maximum.
Does Bullet Central tune FX rifles before shipping?
Stock FX rifles ship with factory Quick Tune System settings. BC Custom Competition and Carbon Fiber Impact M3 packages are assembled in-house with BC Custom shroud, tungsten hammer, and Power Block upgrades.
