Magpul PMAGs in a S&W mp15

[smoke 8]

I own a mp15 by S&W. I have read that the magpul pmags will not fit in the mag well sometimes or with certain rifles. Just want some feedback from other m&p 15 owners who use or have tried to use the magpul pmags. Any trouble or problems fitting into rifle? Just want to make sure they fit before purchase.
Thanks:

It all depends on the bevel at the front of the magazine well. If your rifle is newer it should work fine with P-mags. Older rifles will have problems. Regardless 2 minutes with a rat tail file on the P-mags and the problem is solved. Seriously.

I would just purchase one P-mag (if you can find it) and try. If you have a problem you will see exactly what it is and how to fix it.

My 15 is new-bought 1 month ago so I hope it will be okay. Thanks
