OK, besides having a good AR, pistol and shotty, I think everybody should have a heavy AR too. Well, I am trying to make a decision on what to do. I currently own a DPMS AP-4 with a 16 inch barrel, not a long range rifle, but will get the job done out to 600 yards maybe (which is fine for me). So far the rifle hasn't given me any problems with all the different ammo I've fed it. All five of the metal DPMS mags work great and the 2 Magpul mags I have open run fine too ( I still have 4 NIW). The only thing I need to do is get a good scope for it now. I also have an Armalite/Eagle Arms AR-10 lower receiver with 5 NIW Armalite 20 rnd gen II mags, with no other parts yet for it. What would you do, get a scope for the DPMS or sell it to fund the AR-10 build? I can really have both unless I slowly get the rest of the parts for the AR-10.
