My experience does not align with yours. Don't have the 5-25 but, have the 5HD 7-35 on a Barrett MRAD MK22 and three other MRADs. Very pleased....clarity, resolution, tracking (verified dead nuts on and repeatable)......impeccable to my old eyes. Selected by SOCCOM for their MK22s after evaluating everything available regardless of brand, country of origin. Best of the best optic value available for my money. Got three of them for under $2100 each plus a free Kestrel 4DOF. There are other great offerings out there, but in my world none provide the performance value.......and, I'm more into performance than value.
