Yes they are.
Short answer, lots and lots of sanding.
Long answer, the slots on the Magwell is too narrow compared to the frame by about .125in. so I had a choice to widen the magwell slot or shorted the bottom height of the frame slot, so I modified the frame (much easier to sand compared to the internet slot in the magwell). The magwel also is too narrow for the frame for about .0.0625 so I had to sand the side of the frame (again much easier to do on the frame instead of the inter slot on the magwell). The radius on the heels of the frame is not matching the magwell either so I had to dremeled the back slot of the magwell to fit (much easier to do on the magwell instead of the frame).
Are those the CZC magwells, and what did have yo do to get them to fit?
