The quality of the primer ammo caps determines the quality of the ammunition. The compatibility of the primer caps with other ammunition components especially the cartridge case and propellant results in the difference between a mass-produced product and one which is specifically matched to a particular system. Only the best ammunition can provide the desired precision from the intended weapon. RUAG Ammotec uses its expertise and know-how to adjust each primer cap to suit specific customer requirements. RUAG Ammotec manufactures Berdan and Boxer primer caps for all current small calibers.
