Our Story

When software developers Jake Wyman and Bryan Haaker experienced a bad day at the range filled with failure-to-feeds, stuck magazines and other issues, they knew there had to a be a simple fix. They took to the internet and found that while these problems were common for gun owners, solutions were hard to find.

Solutionists and innovators by nature, the long time friends decided to try their hand at making firearm accessories that would enhance existing platforms. What started in 2012 with one part in a home office has since grown into a top tier brand in the rimfire competition market.

Today the TANDEMKROSS team continues to grow and innovate in their New Hampshire facility.
