When we started thinking about ReShell back in 2019, it was more of a personal project than a business idea. As a family of four with two young kids, our interest in firearms was more about safety and preparedness than anything else. But traditional firearms training posed some obstacles: between the hefty recoil of a 12-gauge shotgun and the logistics of making it to the shooting range, training felt less accessible than it should have been. So, we wondered: could we create something that offered realistic training while being safer, affordable, and usable closer to home?

Our initial prototype—ReShell v1—(Pic 1: ReShell v1 internals) was a straightforward, air-powered training cartridge. We drew from familiar airsoft designs, incorporating a carry-over valve system that had worked well in airsoft applications. But when it came to enduring high-pressure air charging, this first version didn’t hold up. During testing, the cartridge would only withstand a few charges before giving out. Although it wasn’t yet the breakthrough we hoped for, we felt a new excitement as we saw our idea take shape in the real world.

That first test might have been a technical failure, but it was a success in fueling our drive to keep going. The challenges and setbacks of that early stage only inspired us to refine and strengthen ReShell, and it marked the beginning of a journey that would lead us to many more versions—each stronger and more capable than the last.

As we progressed in ReShell’s development, our focus shifted toward creating a paintball-friendly valve system that integrated compatibility with paintball bottles and air lines. This change marked a significant improvement, as it drastically reduced the charging failures and leaking issues we had encountered in earlier prototypes. Inspired by the flexibility and rechargeability that paintball systems offered, we developed what we now call CADS—our Compressed Air Delivery System.

Originally named the “Grip Filler” (Pic 2)due to an early design is a grip style, CADS evolved as we simplified the design to enhance user experience. 

The first iteration of CADS retained a grip design, a feature that worked well with early versions of ReShell’s valve system. However, as we made significant updates to ReShell’s valve, it became clear that our original charging method was no longer compatible. This realization led us to rethink the entire structure of CADS. Switching to a streamlined tube design, CADS now offered a safer, more practical charging solution, perfectly aligning with our goal of making ReShell both reliable and user-friendly.

The new tube design wasn’t just safer; it also enhanced CADS’s compatibility with standard paintball air lines, making it easier than ever to connect and recharge. This seemingly small shift was a major turning point. CADS now provided a stable, consistent air source, offering quick and simple air refills and opening up new possibilities for flexible, accessible training. (Pic 3)

The Journey Continues: Expanding ReShell’s Potential

Our development journey with ReShell is far from over. The addition of the 40mm adapter expands ReShell’s versatility, enabling training across different calibers. This new functionality also allows us to explore a range of projectiles tailored to various training scenarios. With the upcoming 37mm adapter and other caliber options soon to be revealed, ReShell is becoming a comprehensive training solution with endless potential.

We invite you to join us on this journey, sharing your thoughts and ideas as we unlock more of ReShell’s capabilities. Together, we’re creating a unique tool that brings new possibilities to training and readiness.

Stay tuned for more updates—and thank you for being part of ReShell’s evolution.
