I'm rocking the MDT magazines in both my CDI (Winnie Model 70) and Badger Ordnance (Remmy M700 hunter) and my Ruger Gunsite Scout. All the MDT work well there. I've also bought the Magpul AICS 5 rounder that came with my bottom (polymer) metal kit from CTCSupplies dot ca. Most happy with every maker of magazines, especially the factory Accurate Mag that came with the Scout rifle. Now I just have to bust open the Dremel and inlet my SPS Tupperware Remmy stocks for that Magpul polymer bottom metal. It's started , the inletting is coming along really well.
Cheers,
Barney
