I had my dealer order me the complete rifle the day they were released at SHOT. I love MRP’s can’t say enough good things about the platform.
It wasn’t more accurate than my Craddock but it was close enough. My Craddock was the most accurate AR15 I’ve ever had, it was benchrest accurate. The MRP was sub 1/2 MOA with everything though which included a couple loads I tried, as well as the factory FGMM. It actually shot my Craddock load great with a load ES/SD so I didn’t even bother developing a dedicated 95gr SMK load for it, I just did a little pressure test going up about a grain to make sure that it was safe and not right on the ragged edge of pressure or something.
The LMT rep also told me that they had done some SS test barrels during development and they were looking at potentially offering some other options which may include SS production barrels and other lengths. Not sure what if anything ever materialized with that but it may be worth looking into.
