The problem with kits is that you can do soooo much better if you invest some time and do your homework. Really you can learn before buying the wrong thing. Figure out what you want and what's out there. Rarely will a kit hit every high point. A couple years ago I was a noob and could have easily jumped on a kit, but fortunately I spent a lot of time researching before buying. Today after learning the ropes I cringe when I see kits.
If you're determined to buy a Del-Ton kit, I'd look at their 16" LW midlength, 1:7, chrome lined and see if you can get their new M16 HPI/MPI BCG. Del-Ton does let you upgrade parts so read up on ARs (ideally for weeks!) and cherry pick the parts you've determined you want. But the problem here is I'm telling you what I want, only you know what YOU want.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
