Will a PWS 308 upper work with a DPMS high rail designed lower?

[buttonbuck]

Wondering if I could put a PWS upper on my DPMS high rail lower.  Thanks

Lower has nothing to do with rail height. there is no high/low lower designation. They are the same. With that said, i have no idea if a PWS upper will fit on a DPMS lower so cant help with that.

I highly doubt it.  As I understand it, our Piston driven AR308 are great for firing cleaner, cooler, and more reliable.  But I've always ben told the downside is that basically everything is proprietary.

Must be a brand related deal, I am still waiting for these benefits on my Sig 716, so far the difference is negligible. It is a jam-O-matic..........
