Brownells, Midwayusa, Joe Bob Outfitters, Palmetto State Armory, Tombstone Tactical, Red Barn Armory, Ebay, just to name a few. Be careful about the AR10 platform; unlike the AR15 not all pieces are interchangeable.

You will hear a bunch of people call a 308 AR an AR10. The only AR10's are made by Armalite. Some rifles use the AR10 design some use the DPMS LR308 design which is what you have. Make sure anything you buy for your gun is LR308 pattern and not AR10 pattern. It can get really confusing sometimes. Also with the DPMS pattern there are two different upper types high profile and low profile. Most DPMS rifles have the high profile upper which most call standard upper. You'll run into this alot when looking for hand guards. If you have a high profile upper and you buy a low profile hand guard if the it has a continuous top rail the rails will not match up.
Here is a link to help you figure out which one you have. Link
