About O.M.A.C.

Old Missouri Arms Company specializes in .22 caliber rimfire firearms, parts, restoration, repair, and information. If you have a .22 caliber rimfire, chances are we have something for you. We are your ultimate destination for everything from everyday ammo to parts for antique models.

Our goal at Old Missouri Arms Co. is to keep history, heritage, and fun alive by providing high quality replacement parts for heirloom and antique firearms. From pawn shop finds to third or fourth generation firearms Old Missouri Arms Co. wants to make sure you have the right parts to ensure these old feats of engineering from a time before CNC can still be safely and reliably utilized. After all there is no better way to recall those childhood memories of plinking cans than using the rifle you, your father, or even your grandfather learned on. There is something special about the patina, the feel of well worn wood, and that same old sight picture as it comes into focus like so many times before. So we encourage you not to give up on that old piece of iron. Let’s work together to get it back in action, to pass it down to another generation, a tangible piece of family history, and instill a sense of responsibility and heritage.

At Old Missouri Arms Co. we are building a catalogue of commonly missing or broken parts from antique and out of production firearms. We utilize modern manufacturing methods to create replacement parts with better finishes and tolerances than the original parts. We have a commitment to you, our customer, to never use Metal Injection Molding (MIM), castings, or additive manufacturing (3D printing) in the manufacturing of our parts. We believe that cheaper does not mean better. We select the most appropriate grade of steel for each part and utilize the proper manufacturing technique to achieve the highest quality finish, the closest match to the original fit and function, and the longest possible life of the part and the parts it interacts with.

If you do not see the part you are looking for in our online catalogue, please give us a call or contact us via email. Parts do not get listed on the website until we have a full production run completed. Your missing part could be in one of the various stages of production and coming soon.
