10/22 aftermarket Magazine question

[aghauler]

I posted this on another 22 Forum but thought I try here also....

What aftermarket 10/22 magazines with metal feedlips were produced before 2000? Is there anyway to "date" this type of 10/22 magazine pre or post 2000? I have Ramline 50 rd mag which have plastic feedlips that seem worn and not working well.

ramline used red or black followers before 2004 after 2004 butler creek went to a bigger font on their mags

eagle mags pre 2004 were all blackish grey then they came out with clear and orange
i remember buying one every couple weeks at walmart for $9 they woudl either split at the seam or the lip woudl chip off i liked the built in quick release they had and the metal rear lock nub and that they held 30
