"Is there a drum mag what has this same part of the top mag ?

"This magazine is perfectly identical to the mags that came with my matrix/S&T rifle. Has worked great and I have skirmished it multiple times. Just the restock is annoying, but that’s evike’s fault not S&T

"I bought this for my EMG/Daniel Defense MK18 and I can confirm this works for the gun, but the feed lips are too tight to use a speedloader with it. My solution was to file down the lips after the warranty expired ( you can do that whenever but it will void your warranty). Also the fill value doesn't unscrew out of the magazine? I was experiencing leaks only while filling the magazine and tried to check the fill valve and I was unscrewing and unscrewing making no progress. This is a magazine that will work until WA/or another company wakes magazines compatible for the MK18. Nothing too special but better than nothing.
