About the PTS EPM1

The PTS EPM1-S 170 Rnd Mid-Cap Mag Short is a cutting-edge magazine designed for airsoft enthusiasts who demand both capacity and reliability from their gear. This magazine, which is a part of the Enhanced Polymer Magazine (EPM) series, is specifically engineered to meet the needs of players looking for a high-capacity, yet compact, mid-capacity magazine. What sets this magazine apart is its impressive capacity of 170 BBs, a noteworthy feature for a mid-cap magazine, providing a significant advantage in terms of sustained fire during airsoft engagements without the need for constant reloading.

One of the standout features of the EPM1-S is its orange mag level indicator, which offers a quick and easy way to check the remaining BBs at a glance, enhancing tactical efficiency on the field. The magazine is built with a high efficiency compression spring and a low friction internal shell, which work together to ensure smooth and reliable feeding of BBs. This design minimizes the chances of jams and misfeeds, allowing players to focus on the game rather than their equipment.

The EPM1-S also boasts several design innovations aimed at enhancing usability and performance. The unique magazine mag well guide significantly reduces snagging when inserting or removing the magazine from the rifle, a critical feature during high-pressure situations. The exterior of the magazine is textured with an EP dot pattern, providing a better grip even in adverse weather conditions. Additionally, the new polymer baseplate is designed with an angled surface and dot matrix for improved handling and customization. The redesigned follower prevents BBs from jamming, ensuring a consistent feed into the airsoft rifle.

Technical specifications of the EPM1-S include its availability in both black and tan colors to match different rifle aesthetics and environments. It is constructed from a durable polymer, making it both lightweight and rugged enough to withstand the rigors of intense airsoft gameplay. The magazine's model numbers are PSA-PT174450313 and PSA-PT174450307, and it is compatible with M4/M16 style rifles, ensuring wide applicability across different platforms.

In summary, the PTS EPM1-S 170 Rnd Mid-Cap Mag Short is an innovative solution for airsoft players seeking a high-capacity, reliable, and user-friendly magazine. Its thoughtful design features and technical specifications make it a valuable addition to any player's arsenal, providing a competitive edge in both casual and competitive play.

Honestly, this is the only airsoft shop I will ever buy from. Their guns are always quality. Their custom work is mind blowing. Their staff is not only helpful, but always happy to help. If you are just starting out or have been playing for years, these guys have guns, gear, and good advice for every situation.
