Who We Are
About Mattson Munitions
Mattson Munitions is a family-owned firearms, suppressor, NFA, thermal optics, and custom rifle dealer based in LaMoure, North Dakota. We are passionate about firearms, predator hunting, quality gear, and helping customers do things the right way from start to finish.
We help customers across LaMoure, Oakes, Jamestown, Ellendale, Fargo, Bismarck, Aberdeen, southeast North Dakota, and the surrounding region with suppressor purchases, ATF eForm 4 submissions, electronic fingerprints, passport photos, NFA transfers, firearm transfers, Vortex optics, RIX thermal optics, iRay, Nocpix, Liberty Precision Machine suppressors, and custom rifle builds.
Because we operate by appointment, customers get one-on-one help instead of being rushed through the process. Whether you are buying your first suppressor, setting up your ATF eForms account, completing a Form 4, choosing the right thermal, transferring a firearm, or building a rifle, we take the time to explain it clearly and make sure it is done right.
We also believe in supporting North Dakota companies whenever possible. Mattson Munitions works with ND-based brands like Liberty Precision Machine, Bloodline Kinetics, and Hell Creek Kustoms because keeping it local matters. When we can pair North Dakota hunters and shooters with North Dakota-built products, that is exactly what we want to do.
We are not a big-box gun store. We are a family-run North Dakota business built on service, trust, education, local relationships, and a genuine love for firearms, suppressors, thermals, and precision rifle builds.
We Make NFA Easy.
