Well, $35 shipped for a used Romanian 40rd mag, I expected it to be at least functional.
Note: It works fine with a follower from another 40-rd mag. I may need to get another follower.
Do 30rd and 40rd mags use different followers? The 40rd follower form a crappy promag mag I had worked fine in there. However, I tried 2 different followers from 30-rd mags and those got stuck also.
