I purchased a used Classic Army Aug with some mid caps and a high-cap. All of the mid-caps have very poor spring tension and won't feed unless gun is turned upside down and smacked. High cap works and feeds fine.

I'm looking for recommendations for (preferrably Canadian) vendor and brand of good/high quality mid-cap magazines. Also, is it possible to find metal mags for this gun or is plastic/polymer the only way to go?

If possible, I'd like to stick to the 100-120rnd range.

Thanks in advance for time and consideration.
