I believe i have used MAG (i think, they're black with HK trades, they look exactly like my real-caps), star and some random ACM mags, all of which are very tempermental and i just cant rely on them, im getting one of the Star l85 supplied mags and see if that works, weird thing is redwolf say the star/ares comes supplied with this mag but on the page it says its for the Shooters L85a2 series does this just mean ares/star? http://redwolfairsoft.com/redwolf/airsoft/Magazines_SHOOTER_AEG_Std_Shooter_130rds_Magazine_for_L85A2_Series.htm
