The 419 rings and ARC rings limit scope roll when mounting. Kinda nice. Is there reason to think they don’t hold up?
via visual and material spec comparisons to the other rings that are known good / known not good, they look more like the good options. given the cost differential to warne mountain tech or sportsmatch, it's sure not going to be me trying them out to verify. i'm generally not on the early adopter side of the market penetration curve.
