First yes I understand Mag ammo limiters are and oxymoron. But I have been working on making mag limiters for 5.56 AR and AK mags, and have just about developed the process. Seems several companies are out there but damn they are charging and arm and leg. If there is any interest I will try and get a video together when I solve it. I want to make these to where they are permanent, but wont require new base plates or springs as many do. But on teh side they could be replaced and old put back in. I am hoping laws limiting to 10 do not pass but many are being forced to not just in Oregon where its up for debate. So anyways anyone wanting to know how to do these themselves let me know. Right now I am working on the hardening process so it will take allot of reloading. I am looking at making them for other manufactures that do not make 10rd or charge allow for them or the adapters. The reversible area is also part of what I am making that way CAL and elsewhere legal but could be switched to the old with old parts. That seems key is the limiter its self can not be modified easily. But if removed the old parts could be put back in.
