DPMS AR in 7.62 X 39 -- anyone have one?

[10-Ring]

I like this version of AR -- I've always like the caliber & I really like the platform -- I have 2 questions;
1 -- I'm contemplating the Bushmaster gas piston conversion -- has anyone tried it for this set up?
2 -- the mag -- not to happy w/ this poly mag Does anyone make a metal mag that will work w/ the DPMS upper?
TIA

Hello. Yes, I have a DPMS 16" free floated 4 rail fluted heavy barrel 7.62x39 upper on a Stag lower.

Sorry, don't know much about the Bushmaster piston kit. I did research the Adam and PWS piston kits. I have not heard of anyone doing a piston set up on the 7.62x39 upper yet.
