Had pretty much the same experience with same barrel. I got the Fox Ridge thumb hole stock and wide forend. Things weren't going too good, so I glass beded everything from one forend screw to the other about half way up on the barrel channel and freefloated everywhere else(about 1/8" clearance). I didn't quite get 1/4 moa like you but it improved GREATLY. BTW, after a very slight amount of trimming around screw holes, this forend works great on any 16" or 21" barrel I,ve tried. Ain't it FUN when sumptin' turns out right. GOOD SHOOTIN', Walt :-D :-D :-D
