You get what you pay for....
The first six times I ran my two 20 round mags they functioned normally, I only loaded 10 rounds. Yesterday I loaded then both with 20 rounds and hit the range.Constant feed issues, the followers were catching ever 2-3 rounds. Stovepipe once, the extracted shell would catch on the live round during cycling. After further examination both mags had malfunctions with the followers. Plan on modifying to attempt a salvage. Conclusion:Do not rely on these magazines in combat, you will have feed issues and die. Spend the money on magpul magazines, you won't regret it.P.S. ran a 20 round magpul at the range the same day and had 0 feed issues.
