Need help finding a freefloat hand guard for a bull barrel

[mrproc1]

Hey Ya'll......
i have a DPMS Sweet 16 with a stainless bull barrel, which has an OD of 1.050 at the receiver. I'd like to change out the stock hand guard for a 15" Keymod style hand guard. The problem I'm having is finding a barrel nut that will fit a barrel that is made for a barrel over 1.00" OD.
I've called DPMS and the suggested call a couple of the main online stores, and no luck....
I'd rather not turn down the barrel, if need be. Does anyone have any ideas on what my options my be!?!??!
thanks for the help!!

Samson makes free floating hand guards that use thermal bushings that clip to any mil-spec barrel nut.

If the inside diameter of the collar part of the barrel nut is too small, you could take it and the barrel to a machine shop. It should be a real easy job to make the barrel nut opening wide enough to fit. Or just ruin a cheap part but it's worth a try.

Edit: did some research into this method and it seems like an accepted practice with thes barrels. Just tell the machinist to make this thing fit over this thing. Should be 15 mins on the lathe.
