Houston, TX – Roni Corporaton, the leading designer and manufacturer of the renown Micro-Roni, PDW-style pistol-to-carbine conversion kits and other firearms accessories, has introduced their newest, most compact pistol-to-carbine conversion kit, the Nano Roni. Like all other Roni conversion kits, owners can install their handgun into the Nano Roni chassis in a matter of seconds without tools, instantly transforming it into a pistol-braced PDW. This configuration increases the pointability, shootability and performance of the pistol.

The Nano Roni is at the center company’s ongoing product evolution and their recent strategic move to U.S. based manufacturing. This is Roni’s most compact and advanced conversion kit. Transforming a standard pistol into a compact, carbine-style platform improves control through greater points of contact, increases accuracy and engagement effectiveness at extended distances. It delivers a precise balance of compact size, reliability, and performance.

“We’re proud to introduce the Nano Roni as the ultimate compact solution for shooters who demand more from their pistol,” said Marc Hinawi. “It combines our proven design and engineering with American manufacturing to deliver unmatched versatility and performance in the smallest package yet.”

Initial compatibility includes Glock 17, 19, 22, and 23, 31,32 and 45.

Additional compatibility is coming soon, including Glock 43 and 48 platforms, as well as select models from SIG Sauer, Taurus, and Canik. This growing compatibility reflects Roni’s commitment to versatility and user-focused design.

The Nano Roni is a complete system. In addition to the chassis for the handgun, numerous accessories are available including magazine holders, light mounts, Picatinny rails, charging handles, optics mounts, slings and even a belt holster. Currently the Nano Roni and its associated accessories are available in black, OD Green and Flat Dark Earth. MSRP for the Nano Roni base conversion kit is $199.00.

COLUMBIA FALLS, Mont. – May 20, 2026 – PROOF Research is proud to announce the launch of PROOF Exponential Twist (PXT), a groundbreaking advancement in rifling that improves durability, accuracy and shootability. As originators of this barrel technology, PROOF Research developed PXT to push beyond the limitations of conventional barrels, backed by extensive military testing and research. Engineered to meet the demands of modern high-pressure ammunition, PXT represents a significant advancement in barrel technology by delivering longer barrel life, improved consistency and enhanced performance.  

As the leader in advanced carbon fiber barrel technology, PROOF Research continues to push the boundaries of firearms engineering through innovation rooted in real-world performance. PXT was developed to solve limitations inherent in conventional rifling design and to create a platform built for the next generation of ammunition and shooting performance. Unlike conventional constant-twist rifling, PXT uses a progressively changing twist profile designed to reduce initial bullet stress while maintaining  rotational stability.

“PXT is a complete redesign of how the bullet engages the rifling during initial rotation. As the industry advances and ammunition continues to evolve toward higher pressures and performance, we set out to address the technological gap between current barrel systems and where ammunition is headed,” said Brandon Hulzebosch, director of sales and marketing. “PXT gives shooters smoother, more controlled engagement that translates into greater consistency and improved performance. We are excited to be at the forefront of modern technology that will redefine barrel performance across the industry.” 

In traditional barrels, the design relies on sharp-edged rifling, and engagement forces the bullet into abrupt rifling. While the conventional approach has long defined rifle barrel design, the excessive stress can create pressure spikes, accelerated barrel wear and bullet deformation. These issues become greater with modern high-pressure cartridges, faster velocities and repetitive firing. 

PXT addresses these challenges through an exponential twist rifling profile that progressively brings the bullet into rotation rather than abruptly forcing it into rotation. Combined with PROOF Research’s proprietary, smoother-edged profile, PXT reduces the twist angle by as much as 95-98% and lowers bullet engraving force by approximately 30%, creating a more controlled and gradual twist progression. 

The result is a barrel system capable of delivering measurable increased performance in consistency and accuracy. Varying with barrel length and application, PXT barrels provide a 30-100% increase in barrel life by spreading degradation over much more of the bore. This redesign supports much higher pressures and velocities without shortening barrel life. Additionally, PXT barrels provide 20-50% improvements in consistency and accuracy across multiple ammunition types and lot variations, helping maintain accuracy across a wider range of factory loads over the barrel life.  

PROOF Research has available barrel options that include barrel blanks, AR barrels and select pre-fit offerings with more coming soon. PXT barrels are also currently available in PROOF Research’s Elevation FDX and Elevation MTR (Mountain Tactical Rifle) FDX rifle platforms in the following chamberings: 22 Creedmoor, 6.5 Creedmoor, 6.5 PRC, 7mm PRC, 7mm Backcountry and 300 PRC. The Elevation FDX has a starting MSRP of $3,499, and the Elevation MTR FDX has a starting MSRP of $3,799.  

With the launch of PXT, PROOF Research continues its commitment to evolving firearm technology through cutting-edge engineering and advanced materials. Designed for military and law enforcement personnel, precision rifle enthusiasts, competition shooters and hunters alike, PXT establishes an all-new category in barrel performance, setting a modern benchmark for what shooters can expect from rifle barrel systems.
