Superior stopping power, easy handling, reliability, versatility, and dependability. These are the attributes that make the shotgun a superior fighting tool. We build our systems exclusively on Remington 870 shotguns. No other system offers the ease of manipulation, reliability, simplicity or availability of spare parts. We offer two packages to cover the needs of any level of operator whether civilian or law enforcement. From our Thunder Ranch package to our full custom Robar Elite, every system is meticulously assembled and tested prior to leaving our facility. We have been building custom defensive shotguns since 1980 and have more experience than anyone in the industry.
