PTS 170rd Enhanced Polymer Short Magazine Mid-Cap for M4 Series Airsoft AEG Rifles

The PTS EPM1-S AEG Magazine is a game-changer for M4 AEG users who demand top-tier performance in a compact form. Built from ultra-durable Dupont Zytel® polymer, this short M4 magazine holds an impressive 170 rounds without the need for winding, offering flawless feeding and high-speed response for every shot.

Perfectly engineered for reliability, the EPM1-S features a high-efficiency spring, low-friction internal shell, and a new follower design that eliminates jams while maintaining feeding consistency—even in high rate-of-fire situations. Its orange mag level indicator lets you quickly see how many BBs remain, while the EP dot pattern texture and updated polymer baseplate provide excellent grip and pouch compatibility.

Compatible with a wide range of Tokyo Marui-spec M4 AEGs, including HK416, PTS PDR-C, Masada, KWA, G&P, and more, the EPM1-S offers elite-level performance and style. Available in Black and Dark Earth, this compact powerhouse also includes a mag well guide to reduce snagging and an angled baseplate that doubles as a monopod for supported shooting.
