I have been using the Magpul AICS mags in an Aero Solus rifle and another Aero action in a Rokstock with Hawkins bottom metal. They work fine for both rifles in 6 CM.
I have used the Magpul and the Amend2s. I am shocked to say, I prefer the Amend2s. Feeds noticably smoother in my Ultradyne chassis/Stag Pursuit action rig.
Edit to add - although both have run flawlessly for me, to be clear.
My first prs rifle was a 6gt impact build in xlr chassis. I ran aics pmags without issue for a short bit. I've ran the 5rd aics pmag in a 22gt hunting rig built on zermatt actions. The pmags didn't play quiet as well with a crf action as they did from the push feed impact.
