First, a shout out to Scott from Libertyoptics - expecting my scope this week! Looking for recommendations on a QD mount - I will be moving it between several rifles so QD is preferred. All are AR platforms with full rail.
if you rtz is critical, i would recommend a bobro engineering mount. they are very different from most QD mounts, but also not cheap.
even the single lever mount they make holds better than the competition, and i am using a dual lever "scar" mount on my 20S.
