KWA K120C Variable Capacity 30 / 120 Round Magazines for KWA ERG / AEG2.5 / AEG3 Rifles (Qty: 3 Pack)

"Not much to say except so far no feeding issues with the mags and the selector switch operates as they should they have been thrown in the dirt dragged through the dirt on my plate carrier taken direct hits on full auto at 10/15 yards and they are still kicking and operating the bolt catch feature which by the way is sturdier than it looks and seems. Definitely carrying more of these on my load out.

"Fit great in my CYMA M4 but won’t fit properly into my Valken Echo. They will go into the mag well but won’t easily come out. Overall they’re good mags.

"Just ordered these mags for my new KWA. I heard that the erg works best with these so you can get the functional stop firing mode like a Gbb. Only thing is that they are kind of expensive but really well made. You can switch it from 120/30 rounds on the bottom with the switch so that's cool for realism.

Pros-
Nice quality
120/30 for realism
Follower goes all the way up for last shot

Cons-
Kind of expensive at around 16$ a mag

"The magazines constantly have feeding issues, I have tried multiple things to get them to feed but always have the bbs getting stuck in there somehow. Besides that they are nice but too expensive for me to keep buying.

2/5 stars until I find out whats jamming the mag
