Specna Arms meets the expectations of clients by presenting the CORE(TM) line of products – an exceptional series of replicas that introduces a new quality to the market. An attractive price in combination with an innovative spring change system as well as high-quality materials make this replica suitable for beginners and seasoned airsoft players alike.
