These are my favorite magazines for the AK-47. They allow the bolt to lock open after the last round or the action is cocked with an empty mag. They are surplus but I believe never really used as seven are still in the oiled packages and one I pulled out to test in both my Draco and my polish Underfolder. I paid a lot of money for these, not looking to get rich here. I would sell them for $45 each, or trade for some windowed PMAGs or PMAG20LRs. The PM system has been funky lately so make sure to also email me at GEF110@Yahoo.com Thanks!
