best place to get 20 round tanker mags ATM is from what a country (around $30 each)

best place to get 40 round RPK mags ATM is from apex (around $30 each)

anyone have a different vendor/source to get 20 rounders and 40 rounders?

Be patient & keep your eyes plastered to the equipment exchange here. I've been looking for 4 20s and 5 40s for a while now. I've seen some good deals, but I've always been 20 minutes late...
I'm almost considering the cheapo Korean 40s as an option at this point. I know the next vendors have Tankers or any good 40s at below $20 per, I'm very likely to break my 'no mags on credit' rule & charge what I want, then set my auto pay up if I don't have the cash in the bank lol.

My Korean 20 rd work ok, but I just got 5 Hungarian Tankers in from W.A.C. and I can IMMEDIATELY tell a difference in quality.

I really like the Tanker mags wish I could find more. Use to get them at AIM for about $12.
