The EP Series products are products purely conceptualized, designed and engineered in-house by the PTS team. We begin with examining a need in the marketplace that our product line does not yet fulfill or that we feel that we can improve on. Throughout the design and engineering process, we consult with airsoft and tactical industry experts and experienced shooters to ensure that the product does not just look distinctive and unique, but also to ensure that the product is practically and ergonomically usable for end user. This includes both airsoft enthusiasts and sometimes actual shooters.
