Bull Barrel Kit
Introducing the FX Bull Barrel kit!
The FX Solid Bull Barrel is engineered specifically for rifles built around the Dynamic Block system, delivering a new level of rigidity, balance, and precision for serious shooters.
Designed for benchrest and PRS competition, this upgrade transforms how the rifle behaves by creating a stronger, more secure connection between barrel and action.
When consistency matters most, stability becomes the advantage.
At the heart of the system is a 20mm solid steel barrel housing that screws directly into the action block resulting in extremely rigid barrel-to-action interface, Improved alignment consistency and reduced harmonic movement. Inside the solid housing lives the trusted FX STX Superior Liner, combining legendary FX accuracy with a dramatically more rigid outer structure.
The new FX Bull Barrel kit is compatible with all existing Dynamic blocks and the new Dynamic MKII blocks.

BUILD FOR THE DYNAMIC BLOCK
20 MM OF SOLID STEEL
The Bull Barrel uses a massive 20 mm steel barrel housing surrounding the FX STX liner system.The increased diameter dramatically increases the stiffness and mass of the complete barrel assembly, reducing the influence of flex and movement while adding significant weight toward the front of the rifle.
For a competition rifle, that additional mass isn't a disadvantage.
DIRECT CONNECTION
Rigidity doesn't stop at the barrel.
The Bull Barrel uses a threaded rear connection that screws directly into the FX Dynamic Block, creating an extremely solid mechanical interface between the barrel and action.By strengthening this critical connection, the complete system becomes one rigid structure—from action to barrel to muzzle.
When the objective is consistency, every connection matters.
BUILT FOR THE COMPETITION RIFLE
The Bull Barrel was created for applications where weight takes a back seat to stability.
Long-range shooting. Heavy slugs. Benchrest. PRS-style competition.
When the rifle needs to remain as stable and predictable as possible, the Bull Barrel provides the mass and rigidity to build around.
STX AT THE CORE
Despite its massive construction, the Bull Barrel remains built around the FX STX liner system.
The precision-fitted liner sits securely within the solid steel housing, combining FX barrel technology with an exceptionally rigid external structure. It's a different approach to the traditional lightweight FX barrel:
Keep the proven internal technology. Build a much stronger structure around it.
