You can order American Defense MFG stuff right from their website.
I would go with the S model (strait up) since the RFB has a fairly long picatinny rail, there is no point to having an excessive cantilever when you don't need it. You can mount it with the levers on the left or right side so it doesn't block the charging handle.
You can get 2 different heights, they have the S (strait-up) and SL (Strait-up - Low) The S is made for an AR15 scope-height above bore, and the S model is more for HK416 type heights, or for bolt guns etc...
The S is 1.47" from rail top to ring centre, and the SL is 1.11" from rail to centreline.
Arms East has the "scout" models in 30mm rings listed on their site (albeit out of stock), but I would go with the Recon (2 locking levers and recoil lugs) just because it's a much more rigid mount to the rail.
For the price on their website, add 20 bucks for international shipping and then about 40 bucks on top of that for duty/GST etc... from the shipping company. Expensive but worth it IMHO.
The cantilever mounts are more expensive than the strait-up mounts, but that's assuming you can get find them in stock.
You could also give Arms East a call and see if they can order one of em in for you on their next shipment since they seem to be a retailer of the ADM stuff.
Awesome mounts by the way!
