[QUOTE="Kevin Purcell, post: 1321855, member: 68323"] It didn't dawn on me that these are ED bins (HD ... wtf ;) ) I suspect they're another in the new Chinese ED bins that are starting to appear. The others we have tried (Hawke Frontier ED and Promaster Elite ED) are very good bins. See also the new threads on Vanguard ED bins and the Bosma (as mentioned above) Bosma is making a bunch of ED bins including a "closed hinge" ED bin and the specs are very similar to the RSPB bin including eye relief are both 17.2mm. FOV is a little narrower (but you can ask an OEM to reduce the field stop and improve stray light performance). Shame they don't provide dimensions. Does the RSPB HD use the center focus for diopter setting (and locking?). That would be another feature match (and one that the Vanguard uses too).
