Caleb Tucker does a review of the PTS TPM-AK magazine for AEGs if they are the recommended for standard Marui-compatible AK AEGs. The PTS TPM-AK Magazine (AEG) is a mid-capacity airsoft magazine designed for AK type electric guns. With a capacity of 155 BBs, it boasts a translucent reinforced polymer body that not only endures harsh field conditions but also allows for easy visual tracking of remaining rounds. The magazine comes with the PTS EPM baseplate for added protection against bumps or drops. It's compatible with a range of AK AEG's, including Tokyo Marui, CYMA, Arcturus AK Series, and many others.
