About Us

We are a Family Owned American company that utilizes American Manufacturers and Suppliers to build our products.  All of our products are proudly manufactured and assembled here in the United States of America.  The inventor of the MBC® has 24 years experience as a firearms instructor and armorer for a law enforcement agency.  He is an active competitive shooter and has been for the past three decades.

We are proud supporters of the National Rifle Association and the 2nd Amendment Rights of every responsible and law abiding American gun owner.

The belief for safe training and responsible firearm ownership along with the passion and strong conviction in the 2nd Amendment, which gives all responsible and law abiding citizens the right to own a firearm, if they choose to do so, are the reasons that led to the development of the MBC®.

The MBC® (Modified Bolt Catch) (Patent Pending) is a Drop-In Modification that will fit all Mil-Spec AR platforms.  It converts the mechanical operation from semiautomatic/auto-loading to single shot/manual loading.  The Bureau of Alcohol, Tobacco, Firearms & Explosives (BATF) and certain States define a semiautomatic rifle as any repeating rifle which utilizes a portion of the energy of a firing cartridge to extract the fired cartridge case and chamber the next round, and which requires a separate pull of the trigger to fire each case.*  While all basic firearm actions require the action to be cycled manually before the first shot, semiautomatic, auto-loading or self-loading, are differentiated from other forms such as single-action or double-action revolvers, pump-action, bolt-action, or lever-action firearms by eliminating the need to manually cycle it after each shot.  The International Firearms Specialist Academy states that any firearm that is not “Self-loading”, is “Manually Loaded” meaning that after firing a shot, the shooter must manually operate something on the firearm, in order to load the next cartridge into the chamber.

The MBC® is designed to eliminate the semiautomatic, auto-loading or self-loading function of the AR firearm.   The MBC® repeatedly locks the bolt in the rearward/out-of-battery position after every shot in a properly functioning firearm.  The shooter will have to manually depress the MBC® lever to load each subsequent cartridge into the chamber which will then require a separate pull of the trigger in order to fire the next round. 

An AR firearm fitted with a MBC® makes an excellent training platform for shooters of all experience levels (law enforcement or civilians) that are new to the AR firearm.  The bolt locking rearward after every shot provides repeated practice of the loading operation, similar to the initial manual loading step of the AR firearm.  It also provides an additional safety step by preventing a properly functioning firearm from automatically loading itself after every shot.  However, it should not be used to replace the ARs' original safety mechanism.  The MBC® also benefits Bench Rest and Precision Shooters that utilizes the AR platform.  It enables the shooter to manually load each cartridge in the chamber minimizing bullet ogive scraping or deformation, as well as, minimizing and/or eliminating case neck, shoulder and body damage due to excessive force exerted by the bolt during automatic loading.

Several States and Local jurisdictions have passed laws prohibiting private ownership of certain semiautomatic AR rifles.  The designation is specific to the fact that the AR rifle is a semiautomatic, auto-loading or self-loading firearm.   An AR firearm fitted with the MBC® is no longer a semiautomatic firearm by definition of BATF and certain States.
