Mason Munitions, Co. (MMC) is aiming to be a household name.

Mason Munitions started as a family run operation after the realization that minishells were the next evolution of shotgun use. Being ahead of the curve, we developed an adapter that fits into standard shotguns, allowing minishells to reliably run through your standard Mossberg shotguns while also providing the added benefit of increased capacity. Being the pioneers in the industry for such products, we feel we have a better insight into this market than most. Mason Munitions wants to be your go to source for your minishell needs.

Brad and Art Mason have over 45 years of experience in manufacturing consumer products and are proudly based in Houston, Texas. We look forward to providing for our local community and gun community alike.
