ruger gsr mags with ptg m5?

[dvp]

I am having a ptg m5 conversion installed on my 700 aac tactical, I was hoping this would make it so i could share mags with my ruger gsr.
someone told me yesterday they didnt think they would fit exactly. Does anyone have any experience with this?
thank you

I use the steel Ruger GS mags in my PTG bottom metal and they work almost as smoothly as my AI mag.
Mine say Accurate mag on them.
