i have the exact rifle you bought and i had a R.R.A handle put on it along with a hogue rubber grip also and i like it very much. i wanted the iron sights and carry handle so i guess im in the minority so to each their own. i think i might try to find a smaller hand guard up front but other than that i dont think i will change anything else. i wanted a smith&wesson MP15 but no one had one in stock then the recent events happened so i was lucky to get my dpms at a decent price i just hope i dont have any problems with it as i see alot of mixed reviews. i guess only time will tell.keep us posted on how you like it.
