Ok so im doing my 3rd build on a dpms striped lower . I already have a dpms m4 and a 16in bull barrel rifle . I guess im lookin for something  different and would like some input  on my other options. I was kinda thinkin a 11.5 w 5.5 or i was also lookin at pencil/lightweight  type barrels. I also am not tryin to drop thousands of dollars either. Im going to try and buy most of the parts of the EE. l8

Go with a Heavy Middy upper .  "Fluted"
