GAHHHH! LOL, I really like the idea of the polymer because i will be walking around with it quite a bit, but as you stated about the duracoat i don't know if it will work. Also to tailgate that dpms sounded great and you said "plus" and i got excited for a second then "it does not have a dust cover" and i was thinking darn I kind of wanted one. Worst part is, as i stated before im one of the youngest people on here. I have to have my father buy the lower for me, if only i could age 2 years faster!
