||I bought one of these for my king arms m933. These lock in nice and tight! of course it wobbles like 2 millimeters side to side but its a free fall mag so no complaints here. You can take it apart in a flash if you need to.
Ease of maintence
120 rounds is perfect! my gun just dumbs the mag really fast.
Ranger plates fit!
cons:if your picky. The mag does scratches easily ( I kinda like the look tho)
No other cons
other than that you should buy one and see if it fits in your gun!
