AICS Pmags?

[PNW EOD]

Has anyone had any experience with the Magpul PMAG AICS style? It looked like they would be a good alternative to an $80 AI Mag, and I've had great luck with the Pmags, but I hear they can require alteration to feed properly? If anyone has any input, I'd be all ears

If your loaded rounds will fit in them, they are OK. Too short for my rifle, so I run Accuratemags.....

I run my 6mm Competition Match at a length of 2.860" in them with no issues.
