These magazines are a solid okay, atleast for me. I currently have a G&G Combat machine with rail system and im looking to get the VFC MK16. First off let me say the lower receiver of the G&G is polymer plastic and these mags are a tough plastic ( idk the name ) i expected no feeding problems but some mags shoot fine or miss fire a little and others its 1 or 2 bbs come out and then nothing. I also noticed when i was test firing at one time i crouched and shot and almost all shot perfectly with maybe a few miss fires. Now it could be because the part where the magwell should lock in place on the indent of the mag is plastic or because the indent on the mag doesnt have lips for the magwell to grab onto. BUT even on my G&G mag that came with the gun inst feeding well so maybe its just my gun getting old. Whatever the case idk but here is my feed back.
IDK how this review thing works ( my first review ) but if anyone can respond with possible fixes to this problem plz do
-sturdy even if its plastic
-no lips for the magwell to grab onto
