Thompson/Center Buys Green Mountain Rifle Barrel Company

Everything’s coming up Milhouse for Thompson/Center these days. In the months after it announced its return to business, T/C Arms has been super-busy reintroducing old favorite models to its lineup. Now, they’ve just announced they’ve purchased the Green Mountain Rifle Barrel Company.


The ultimate fudds @ TFB:

A sensible purchase

It may shock some readers to hear that not every company with a name on a product makes every part of that product. In the case of Thompson/Center, when current owner Gregg Ritz previously owned the company in the early 2000s, T/C Arms worked with Green Mountain Barrels on options for customers of the single-shot brand. One of the foundations of Thompson/Center’s business model was the ability to buy drop-in replacement barrels for their guns, allowing the shooter to have a single firearm capable of firing multiple rifle and shotgun cartridges.


When Ritz bought T/C Arms back in 2024, he started rebuilding the company to what it was before Smith & Wesson changed up its production processes, and part of that job was restoring ties to the Green Mountain Rifle Barrel Company. Now, Thompson/Center has acquired its partner.

The road ahead

Not much should change for Green Mountain’s customers; the press release for the acquisition says it will still operate as an independent entity. But inside the reborn T/C Arms, they now have a vertically-integrated operation that can not just pick up where they left off with their muzzleloader and modern centerfire models, but help them develop new products that reflect current cartridge development.

“Bringing Green Mountain into the T/C family is a pivotal step toward reclaiming our legacy and controlling more of our craftsmanship in-house. We are extremely proud to join forces with the talented team at Green Mountain, empowering their capabilities and implementing new machining innovation, all made right here in New Hampshire,” said Ritz at the announcement. “We look forward to continuing to serve existing and new Green Mountain customers in the firearm community as we raise the bar for quality and service.”


Stay tuned; it will be interesting to see how T/C Arms can move their products forward now that they have this manufacturing partner permanently baked into their formula.

    Thompson Center, the company that makes nothing and sells nothing, buys out a producing company in order to shut it down.

      Thompson Center's CEO already told Green Mountain Barrels they will be discontinuing some of Green Mountain's barrel offerings.

      They were shut down by Smith and Wesson in 2021 and will start making new firearms again later this year. So it’s been a bit.
