Hi all,
I am curios about changing the lower on my 10 with 80% lower. I have been looking at the UFS .308 but I cant get any info from them. I Believe they are a standard DPMS billet milling, will the M&P upper mount to that lower?

White UFS Billet Aluminum 80% Lower Receiver

I honestly can't remember. I believe the M&P10 lower is non-proprietary but I can't say that 100% for sure. Do you know anyone with a DPMS that you can try fitting your upper to before you buy?

I did try it with an aero precision upper and it did not fit. The ambi mag release had interference issues with the aero since it is not rounded and is more squared off. What I really need is a DPMS lower to try on my upper I guess.
