DPMS style .308 upper information needed!

[VaderSpade]

I have a Tactical Machining DPMS .308 style lower put together (from an 80%) and ready to go.
I have been trying to find a .260 Remington upper, but have had no luck. I talked to DPMS and they said they haven’t seen one go through in quite a while, but maybe they could get me one in a few months.
Not fast enough so I just ordered a .260-barrel.

What I’m looking for is good sources for all the other stuff I’ll need.
Stripped upper, gas block, gas tube, rails, etc.
If you have experience with the DPMS .308 platform help a guy out.
Thanks

P.S. I know what parts are interchangeable on the lower. What AR-15 upper parts can be used???

The DPMS website sucks but they have a whole catalog and sell all the individule parts you will need for your build. Look closely at the barrel nut and make sure the tube/rail size matches. Good luck and post pics when your done.
