RFM Armi born in the heart of the Val Trompia, an area that has been the global benchmark for Italian gunmaking for centuries. The company has chosen to develop its own manufacturing philosophy, focusing on innovation, ultra-precision machining, and a fully customer-focused service. Each weapon is designed to offer high performance, maximum reliability, and a level of customization rarely found in the sporting firearms market.
The SK One 25 represents today the flagship model of RFM's clay shooting production. It is an over-and-under shotgun developed for the Trap, Sporting, Skeet, and Electrocibles disciplines , capable of combining extremely refined mechanics with artisanal construction quality and a technical package that satisfies even the most demanding competitors.

Modern design and four color configurations
From the very first glance, the SK One 25 conveys a strong aesthetic personality. RFM has developed a platform that allows the shooter to choose between four different color configurations.
The rifle is available in the elegant Total Black , Blue , Orange and Green versions , where each colour is harmoniously reflected in the writing on the receiver made with ceramic enamels , in the trigger and in the buttplate, creating an extremely refined and exclusive ensemble.
Mechanics completely machined from solid
The SK One 25 is a gun built without compromise. All the main components of the battery are machined entirely from solid , ensuring dimensional precision, robustness and a build quality designed to last over time.
Great attention has also been paid to the trigger group, which can be calibrated directly to the customer's needs , allowing for a perfectly personalized response based on the shooting style.
The battery is also removable and can be removed extremely easily using a practical release pin , making maintenance and cleaning operations easier.
The prestigious Boss closure
One of the most technically refined elements of the SK One 25 is represented by the prestigious Boss closure , a mechanical solution considered among the most advanced in the panorama of high-end over-and-under shotguns.
This system guarantees an extremely solid closure, optimal stress distribution and long life even after tens of thousands of shots, features particularly appreciated in competitive use.
Fully interchangeable components
The RFM design philosophy also aims for maximum simplicity of maintenance.
All the main components subject to wear are in fact completely interchangeable, including the action pins and the barrel pull rod , allowing the gun to be kept in perfect working order over time.

Cerakote today, DLC tomorrow
To ensure maximum surface protection, the SK One 25 uses a modern Cerakote coating , a treatment that offers high resistance to wear, corrosion and atmospheric agents.
RFM also announced the future introduction of the prestigious DLC (Diamond Like Carbon) treatment , a technology used in the most advanced sectors of precision mechanics and destined to further increase the surface hardness and smoothness of components.
Latest generation titanium chokes
Great attention was also paid to the choke system.
The SK One 25 features ultra-light titanium chokes , one of the most technologically advanced solutions available on the market today.
The use of titanium allows for a reduction in the weight of the barrels while maintaining extremely high mechanical characteristics and excellent durability over time.
Adjustable Ergal rib
To perfectly adapt the gun to the shooter's style, the SK One 25 can be configured with a high or low rib , both made of Ergal.
The adjustment system allows for five different configurations , easily modified using a simple key supplied directly inside the gun case.
A quick and practical solution that allows you to customize the setup without having to resort to complex interventions.
Fast Barrel System by RFM
The rods are one of the strong points of the SK One 25.
RFM has developed its own Fast Barrel System , a solution designed to guarantee excellent ballistic performance, consistency of fire and speed of target acquisition.
The over-and-under is available in 12 gauge with 70 mm and 76 mm chambers , allowing the shooter to choose the configuration best suited to the discipline practiced.
The added value: RFM customer service
One of the aspects that most distinguishes RFM Armi it is the direct relationship with the customer.
The company offers an exclusive service for the creation of completely custom-made stocks , designed according to the physical characteristics and needs of the individual shooter.
The customer can personally choose their own stock from a vast selection of high-quality, fine-grained woods , selecting the essence, grain and aesthetic level before the final processing.
Each stock is then made according to the shooter's anthropometric measurements, ensuring perfect ergonomics and an extremely natural shouldering.
Custom hand-made engravings
For those who want to make their SK One 25 a truly exclusive piece, RFM offers the possibility of requesting completely personalized engravings done by hand.
The works are entrusted to the master engravers of Val Trompia , authentic artists of the Italian gunsmithing art, capable of transforming each weapon into a unique specimen through decorations made according to the best artisan tradition.
