I bought a Bravo and can therefore answer my own question. The slot for the lug is 0.50" wide, which will accommodate most any recoil lug, especially mine at 0.25".
About the stock: 1) The front action screw is captive to the stock. In other words, it doesn't come out when unscrewed from the action. 2) The mag well is a little snug and the AICS magazine does not drop free. The instructions say this can be adjusted, but not how, and I unscrewed every screw from the fore-end expecting the plastic skin to slide, but it did not and I didn't force it. 3) The front action screw hole in the stock is deeply recessed in a 1/4" diameter hole. I didn't have a bit that would accommodate that width and depth in my Borka set, so I turned down the diameter of a long hex-shafted bit for torqueing the action screws. 4) In a perfect world I would prefer the cheek riser rods to be spaced further apart. As is, the are nearly a single pivot point against the riser rocking forward (ever so slightly) under forward-downward pressure when nearly fully extended. But to space them wider would require a bigger clamping system like the KMW Loggerhead.
Given that I replaced a Magpul Hunter stock with this, I think the Bravo is certainly an upgrade. There is a lot to like about it as part of a budget-minded setup.
