Where did you get your reproduction 2A1 magazine?I modified a reproduction 2A1 magazine for my DCRA No.4. After the mods it's even able to feed empty cases. Cost was 100$
As mentionned by Claven2, it was one of the ones from Numrich (Gunspartscorp) in the US. Keep in mind it wasn't a drop-in, I had to modify the feed lips and the magazine's feed ramp a bit.Where did you get your reproduction 2A1 magazine?
