Granted, it took several years of hinting for the Wilcox PVS-14 bridge to be released to the commercial market - but there have been "hints" of a newer, lightweight dual-PVS-14 bridge by Wilcox coming to market in the near future.
Personally, if I were still running dual PVS-14s, I would wait for that, or if nothing else, get the cheapest bridge I could use in the interim, then drop the change on the lightweight Wilcox bridge.
Their current bridge, though I've not handled one, looks, to borrow the phrase, "like a marvel of engineering," but according to the stated specs, it's also the heaviest PVS-14 bridge on the market.
Not for nothing, dual PVS-14s are a pretty heavy setup to begin with, cutting weight where ever possible and as much as possible is, IMHO, a very worthwhile pursuit. I used the N-Vision bridge for a while before getting MOD-3s, and I was very happy with it all things considered, even though it didn't have as many of the flashy features as other bridge mounts - it was far lighter.
