I’m Jeff, the owner of BT Gun Company based out of Rubicon, WI. By day, I’m a Senior Quality Inspector dealing with military stuff that makes a loud boom, but I run my FFL and repair shop because I love the mechanical side of firearms and want to offer my community a better deal without the retail runaround.

I specialize in custom AR-15 builds, working heavily with billet lowers like the CMMG Mk3, and diagnosing tricky gas system or cycling issues. I also handle general maintenance, upgrades, and repairs for shotguns, hunting rifles, and handguns. When I’m not at the workbench, I’m usually out at the Union Rod and Gun Club.

For folks in Dodge or Washington County (Hartford, West Bend, Slinger), I offer straightforward $25 long gun and $35 handgun transfers. I also have direct dropship lines to optics and gear, allowing me to beat big-box retail prices on red dots and thermals.

I’m on here to talk shop, troubleshoot builds, and help locals get what they need. Feel free to reach out or check out btgunco.com.
