Poor customer service from cmmg - CMMG, Inc AR-15 .350 Legend Magazine

I have both the 10 and 20 round magazines.
10 round unit has an anti-tilt follower and feeds great. The 20 round units do not and so they do not feed properly. I swapped the followers between the 2 units and the feeding issue followed the shorter follower. I contacted CMMG customer service... they were quick to respond but offered no solution to fix the issue. They wouldn't even sell me the 10 round followers separately. I had to purchase some followers marketed for 223/5.56 to fix my issue.
So, if you're having feeding issues with their 20 round mag, buy some of the anti-tilt units offered by another manufacturer (hint, they offer them in Yellow or Green). Unfortunately, they only hold 16 rounds now, but they work.
If they offerrd a 30 round magazine, you'd probably need to fix them too.
You'll end up with a 26 round mag but it will work ���.
