When Ken Trapp talks about his Idaho-based company Salmon River Solutions, there is a tone of pride and dedication in his voice that comes when someone creates something with their own hands from the ground up.
For Trapp, that pride and dedication can be traced back to a childhood spent around milling machines, where birthdays would at times happen alongside humming equipment and the sound of machinery, which he described as being both familiar and comforting.
“There’s a picture from my third birthday where I’m sitting on a milling machine while my dad was doing a setup,” Trapp said. “He was so busy he couldn’t come inside, so we opened presents right there with him.”
Trapp was known around town as “Bruce’s kid,” the son of a respected precision mold maker who was well known throughout the area. By 13, Trapp was working in that same shop, and by 18 he was learning to machine full-time. Though he never planned to take over his father’s business, the time spent there shaped his understanding of craft, precision and what it means to build something that lasts.
His early career landed him at MacKay Manufacturing, where he learned how to produce parts quickly, accurately and at scale. Those lessons, combined with the hands-on learning of his youth, formed the foundation for what would become Salmon River Solutions.
Today, the company has come to be known across the hunting and shooting world for its innovative accessories, titanium muzzle brakes and hybrid Arca plus Picatinny rails.
Despite all his knowledge of machining, many of Trapp’s inspirations came from the outdoors and networking with people of like minds and passions.
Trapp grew up bird hunting, sometimes as many as 35 to 40 days a year. He would awaken at 3 in the morning to meet his uncle and their dogs for long days in the field. Since he didn’t have many friends who enjoyed hunting upland birds, Trapp was eventually pulled into the world of big game hunting and long-range shooting, which in turn led him to participate in online forums that brought precision-minded hunters and shooters together.
Forums like Rokslide, Long Range Only, and Long Range Hunting became the bases for his curiosity and innovations. They also became a conduit for Trapp to hear directly from hunters and shooters regarding what they needed in terms of accessories for their rifles, particularly when it came to shooting long distances.
In the evenings after work, Trapp began to design, mill and prototype his new ideas. One of his first concepts, a combination Arca and Picatinny rail, would grow to become one of the company’s signature innovations.
“I can say I was the first one to ever design and manufacture a combination rail that had Arca and Picatinny,” Trapp said.
As he started posting his designs and products to forums, hunters responded quickly. It was at that point that Trapp realized he was making the right products, at the right time, for the right people.
Soon Trapp and longtime friend Zach Lester, who is also a machinist, partnered to formally launch Salmon River Solutions in Post Falls, Idaho. Their handmade titanium muzzle brakes, and the early Arca rails, quickly found traction with outdoor enthusiasts who were looking for lightweight, dependable solutions that were manufactured in the United States.
One day, a phone call came, helping to launch the business into a new phase.
The general manager of Outdoorsmans, a major retailer, reached out to Trapp. He took an $18,000 purchase order for nearly everything the company made. Trapp explained that the timing couldn’t have been better.
“That was literally two weeks after I decided to do this full time,” he said.
As sales picked up, Trapp’s identity as both a machinist and hunter began to shape the company’s direction.
“Almost all of our products come from being out in the field,” he said. “We’re hunting and we’re at shooting competitions and seeing what we’d want as shooters. If I need it, there’s a good chance other people need it too.”
As a result, an innovative spirit became more of a reflex.
When friend and Rokslide co-owner Ryan Avery encouraged him to produce titanium muzzle brakes, Trapp partnered with him and tapped into the forum’s extensive network of hunters and outdoor professionals to drive forward the design. When hunters began shifting from Picatinny rails towards Arca, Salmon River Solutions was ready with combination rails that allowed shooters to use the same setup on both tripods and bipods. And when suppressor use took off over the last several years, Trapp and his team began designing suppressor-mounted brakes to reduce recoil and keep hunters on target.
The company’s product line has grown alongside the surge in lightweight rifle builds, modular rifle platforms, and the rapid adoption of Arca tripod shooting in both competitions and hunting.
“We started the company at a really good time,” Trapp said. “Tripod shooting was just starting to get popular. A lot of people still don’t know about clamping an Arca rail into a tripod, but it’s growing fast.”
Today, Salmon River Solutions shares a building with Unknown Munitions, Unknown Suppressors, and Shoot to Hunt, forming a cluster of companies that benefit from the same manufacturing floor, a shared culture of experimentation and end-user-based determination. Between sponsored shooters, competition partners, friends and hunters from throughout the world, the ideas never stop coming.
On the manufacturing side, Salmon River Solutions stands apart for using 7075 aluminum in its Arca and Picatinny rails, a material that Trapp said is about 60 percent more rigid than the more commonly used 6061.
“It presents a more stable shooting position when you’re clamped into a more rigid rail,” Trapp said.
The company also listens closely to customers. When hunters repeatedly asked for integrated QD cups, Salmon River Solutions redesigned its Hunter Rails to include them.
“We’re not just leaving products how they are,” Trapp said. “We’re consistently updating and improving them.”
Challenges have come mostly from the realities of being a small manufacturer in a fast-moving market. Early in the company’s evolution, Trapp wished he could have patented the original Arca plus Picatinny combination, but the company didn’t yet have the money. By the time it did, competitors had already copied the design.
“We’re at least the original one and the most popular one,” he said.
What began as two machinists now includes seven employees, and Trapp spends hardly any time designing and machining parts compared with what he once did.
“It’s been weird,” he said of his evolving role in the company. “I haven’t designed a part in probably two and a half years. I do miss it some days. Now, I handle the business side and help on the floor, but there’s always a lot going on.”
Looking ahead, Salmon River Solutions plans to continue expanding its reseller network and increasing brand awareness. The company is already in Scheels and is working to get into EuroOptic. A move to a larger shop is planned for January, which will triple its current floor space.
No matter how big the company becomes, Trapp’s goals stay simple.
“We’re trying to stay humble and come out with good products that help people,” he said.
And in the end, that simplicity is the conduit that connects Trapp’s third birthday on a milling machine to the shelves of major retailers today. It’s a life shaped by craftsmanship, by long days chasing birds and by the shared language of hunters who appreciate tools built by someone who understands them. The work is personal, just as it always has been — one idea at a time, built on a foundation grounded in a lifetime of work that started with a kid sitting on a milling machine on his birthday beside his dad.
