centurion MK12 or HCS?

I have seen good things from both but I also read one very in-depth and bad review for HCS. High caliber sales, Does anyone have either of these uppers and what do you think of it? Thanks guys

I had HCS build me a MK-12 Mod 1 with a Noveske barrel sold by MSTN . Couldn't be happier.

How about Precision Reflex?

I’ve always heard good things from the local guys that have them.

I have a HCS Mod 1 and a Mod 0 I pieced together with a WOA SPR. The Mod 0 was a little better shooter till about a yr ago, consistently shooting sub moa with 75gr hornady handloads. It has opened up to a little over moa since, reason unknown to me. The HCS is right about moa or a little over with the same handloads and both shoot cheap 55gr hornady fmj handloads well. I bought the Mod 1 used with supposedly very low rd count on another forum and have never dealt directly with HCS.

All three have a solid claim to a personal connection to the Mk12 program. And all three get glowing reports.

I have a Centurion and its been a good shooter. 1/2 MOA or better with my 75 and 77 grain handloads and sub MOA with Hornady match 75 HPBT loads. It didn't like Black Hills 75/77 in the blue box for some reason. With 55's its about 1.5 MOA or just under depending on the brand.
