ICS 300rd Hi-Cap TMAG H300 for M4 / M16 / L85 Airsoft AEG Rifles (Color: Black)

"Feeds flawlessly in all ICS AEGs and can confirm it also works in Maruis (non recoil shock), Classic Army, Star and KWA. Plastic feels nice and is not so light as to feel brittle nor too heavy to be annoying.

"Works perfectly in ICS AEGs. However, it will NOT feed well in Soft Air or G&G Wild Hog M4s due to how loose it sits in the magwell, so double check your weapon's manufacturer before buying. Otherwise is high quality with durable construction, a useful and well placed fill indicator window, great aesthetics and long lasting winding.

"Work well. I tried the KWA K400 as well (from amazon) and returned to purchase these. (These are the same ones that come with my rifles.)

"These are good mags, feel sturdy, feed well and look cool.

Pros:
Robust
Feeds well
Has a clear strip you can see how much bbs are left
Winding lasts for quite a bit
