Yep. Instead of the 45 degree offset mounts and traditional BUIS, he could get a set of these like I plan on doing for my RRA with Zeiss 3x9 scope. They are going to take me a little while to save for but they seem to be the only one their kind.
I just found these cheap Airsoft ones. I wouldn't trust them but I guess they are only 10% the cost of the KAC's.
