Rear bag for an AR with Caldwell Fire Control front

[pdice]

Does anyone have suggestions for a rear rest for an AR with an A2 stock for a Caldwell Fire Control Rest. I bought their standard rear bag but it wasn't tall enough. I wasn't thrilled with it, it seemed to be too flimsy, but I'm not experienced at all with benchrest shooting.

Check out the Protector line of rear bags.
Sinclairs have them and others

I use Protektor bags too, have a small collection of them, and none of them are really tall enough with a Caldwell Rock BR (I know, not the same rest). I use wooden shims underneath, I bought a couple off a buy on benchrest.com with varying thicknesses and anti-slip material on the tops and bottoms. Those who are more inclined could cheaply make them themselves. ;D

Also consider using the EGW bag riders for AR-15's.
