Pictures of all the stocks and muzzle brakes are on Robinson's website, http://www.robarm.com/
I have the light barrel, folding stock version with an ACOG and Troy Industries BUIS. I have no problem getting a good cheek weld on the tube stock. There are a number of ways to add pads to these tube stocks and Alex is about to come out with his own version of a non-tube stock. Here's some pictures of mine.
In this next picture you can see the height of the ACOG above the tube stock. It's more of an upright head position than the canted over cheek weld I have to use on my Weatherby. Bottom line though is that I don't have a problem with it.
