from what i’ve read seems like it has all the necessary stuff nothing I can’t live without for awhile
There are so many qualified to speak to Del-Ton, but from a newbie to the non-Colt AR-15 world, it looks nice to me. I’m having Anvil Arms build me something very similar with a few added tweaks and a lifetime guarantee for about the same dough, plus I get to actually speak to the guy who is making it… 
Just something to consider…
