been looking to pick up an AR.
reviews on the S&W MP-15 seem pretty decent for the money and I could get one for like $600 out the door.

my question is ,
if I grab one will I be dealing with proprietary parts with this model?
one of the selling points of the AR platform is the interchangeability of parts across manufacturers

while I think the S&W fits my needs sufficiently i'm willing to look elsewhere if it will prevent expandibility.

It will be compatible with other "mil spec" parts.

Good no frills guns.

Is there anything you must have on an AR carbine?

You can add it later

The Ruger AR15 use proprietary parts...the MP line is GTG if you get the I or the II.
