A new remarkable design feature unique to this EPM as it allows the end-user to immediately know if the magazine is fully loaded by seeing the orange follower appears at the small see-through window which is located at both side of the shell.   The extended baseplate provides a better grip and more control while drawing from the pouch. Securely screwed at the bottom of the magazine, a marking matrix is implemented at the bottom of the baseplate for magazine identification use.      Compatible with G&G ARP9, Classic Army PX9 AEG. ​ Features: BBs bullet full load indicator EP dot pattern texture for better grip Extended polymer baseplate with dot-matrix PTS signature follower prevents bbs jam ​ Specification: ​ Colour – Black Material – High-Performance Reinforced Polymer Dimension – 38 (L) x 24 (W) x 258 (H) mm Weight - 162g approx.
