OK, second time around.  You guys have been so very helpful in getting me the perfect gear, but no one has touched this one.  Here goes again:  Have a Bushy flattop upper.  Want to be able to mount my CMO Elite IR scope on there (it is the model with the Weaver mount).  It is too low.  How high does it need to be, what would be the best QD mount (I'm thinking of an ARMS 19 as it would be versatile with other things).  How much would the ARMS 19 raise the whole setup?  Suggestions please, or if I need to provide more info, I'll be happy to.  Thank ya'll,

I have the Rock River Arms riser and it works perfectly for a scope that I have mounted on a Bushy flattop. It is surprisingly good quality even for 35 bucks.  It raises the scope about 3/4 of an inch. Not sure how high you'll have to raise the CMO though but its probably close. Quick removal/install too. http://www.rockriverarms.com/  http://www.rockriverarms.com/scope_mounts_slings_&_bipod.htm
