Our Story — New England Arsenal
Built on Experience. Driven by Innovation. Engineered for Precision.
New England Arsenal was founded with a simple mission: to design and manufacture innovative, high-quality firearm accessories that solve real problems and improve performance.
With over 15 years of experience in the firearms industry, our founder brings a background in mechanical engineering, product development, and manufacturing. From concept development and prototyping to rigorous testing and production, we've spent years turning complex engineering challenges into practical, reliable solutions.
New England Arsenal was born from a passion for creating products that we believe should exist but aren't always available in the marketplace. Rather than settling for what's already out there, we take an engineering-first approach to identifying opportunities, improving existing designs, and developing innovative accessories.
Based in New Hampshire, we're a small, independently operated business with big ambitions. We focus on thoughtful design, precision manufacturing, and delivering exceptional value to our customers.
Our growing product lineup includes accessories for the SIG Sauer Cross, Ruger American Gen 2, and Ruger 10/22 platforms, with new products continually in development.
At New England Arsenal, we believe great products start with great engineering.
We're proud to bring our experience, creativity, and attention to detail to every product we offer.
