You saw my comments in the other thread. So no need to repeat here. I will add that S&W offers a lifetime warranty. So, if there is an issue, they should fix it. As long as the rifle is stock.


I don't know enough about Rock River AR10s to comment.


Armalite AR10s follow a different format from LR308/LR25 format rifles. So, your parts options will be limited as a result. As far as I know, they are the only one to use that format.


I've seen some good reviews and comments on the DPMS. There have been remarks that they are heavy though.


Your best bet might be to get some reviews and gear reviewer comments on them outside of manufacturer specific forums. Asking about other brands on a S&W forum might not get all the answers you want or need. Kinda like asking a Dodge forum about Ford or Chevy trucks.
