I have a lot of experience with the AR platform over the last 30 years. I have/had a 16" RF in 5.56 that came to me brand new at a smoking price, it did run fine but the accuracy is the worst I have ever seen in an AR platform rifle, 8-10" at 50 yards is the best I have gotten out of it. I have run 50-69 grain commercial ammo including several "match" loads with 2 different known good optics, with and without muzzle devices, etc. The magwell is undersized enough Magpul magazines won't fit without pounding them in and yanking them out, GI mags work with no issue. The lower is also narrow enough internally that my modular triggers won't fit, I tried AR Gold and CMC triggers and neither will fit. So, with a total of about 80 rounds through it I salvaged the handguard which I like a lot, BCG, upper receiver and stock assembly for a build with a DD 16" chrome lined barrel, it shoots 1.5 MOA for 10 rounds out to 200 yards with M193. The upper receiver will get replaced at some point, it took over 25 MOA from center travel to zero, ray charles could see that the pic rail isn't machined inline with the axis of the upper. I never contacted RF regarding the issues with the rifle, for what I have in it I am not upside down after salvaging the parts I did. It's probably a bad crown on the barrel that could be easily fixed if I cared to use it and the other issues with it could be worked around. All that said, I have seen several other RF rifles similar to mine that run and shoot OK, I know of 1 that will shoot right around 1 MOA out to 200. 2 PSA in 5.56 and one in 308 I have all shoot 1.5 MOA or less, the 308 substantially less. If I was on a budget or building a beater I'd buy another PSA without hesitation, if I wasn't on a budget I'd buy another JP, White Oak, Rock River, etc,.
