Cool mag I guess. Only used a few times. These are steel, not aluminum. The front slides down to load/unload or it can be used like a normal mag loading from the top. $30 or trade for 2 standard GI 30 or 20rnd mags and ill give you $10. or trade for 1 gi mag and give me $10. in aloha. Also interested in reloading components. (.223/.224 or .40/10mm bullets) Also interested in small rifle primers. I would also throw in a few .380, .25 auto, 38spcl or some loose mixed 22lr if you have something that uses it, I don't.
