DPMS uses Magpul magazines. I think Armalite has gone to these type magazines also. Rock River once used FAL magazines. I've seen the DPMS at Acadamy Sports, a local gun store, and Gander Mountain for around $1,200-1,300. That leaves money for scopes or other accessories. I've also heard some say they got 1/2 moa out of the box. They seem to be a little front heavy with the colapsible stock. Standard AR stocks seem to be more balanced. I also think they are all eventually going to use the Magpul type magazines. Several companies have adapted it. I have an AR-15 DPMS and I like it. No problems so far. DPMS/Remington also make uppers for 243, 260 Rem, 7mm08, 308, and 338 Federal. So you get a lot of options if you want to go that route. Someone will eventually make it in a 358 also, from what I have read. All of these cartridges use the same magazines, so that won't be a problem, like some calibers for the AR which require different magazines or magazine feeds.
