7PRC feeding issues Magpul AICS

[Del Gue's Mustache]

Recently started shooting a 7PRC (rebarreled from 7mag) R700. Feeds fine from the expensive accurate mags but most of the Magpul AICS mags don’t feed very well, the rounds keep diving forward and the followers are binding up inside the magazine, I’ll see if I can recreate it and attach a picture. Anyone having a similar problem?

I just saw this on a build I did. Only happened as I was shooting, recoil was moving the rounds forward in the magazine. I found another thread that talked about stretching the mag springs, they said it fixed it. I tried it but haven’t been able to shoot it again yet. I tried hitting the nose of the stock to simulate recoil with one mag that I stretched the spring in and one I didn’t. It seemed to fix the problem.

I’ll give that a shot, thank you
