buttonbuck Report post Posted August 9, 2017 Wondering if I could put a PWS upper on my DPMS high rail lower. Thanks Quote Share this post Link to post Share on other sites
blue109 Report post Posted August 10, 2017 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. Quote Share this post Link to post Share on other sites
EZTundra77 Report post Posted December 3, 2018 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. Quote Share this post Link to post Share on other sites

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..........
