I like the Choate stock very much, the ergos are GREAT and the constuction is solid as a rock...and even more, I like the fact that the AO's beautiful wood stock is stowed for safe keeping.
That said, it did take quite a bit of roto-tool work to get the proper fit, no it did not "drop in" fit by a long shot. Turns out the area behind the FCU need to be significantly trimmed out. It has a good fit other wise.
okay the good stuff
