The dou is perfect, consistent with rifles in the L-block and surrounding blocks. The bcd/4 TG is right, the lock screw and without seem to intermingle, but all are qnw if STG. As said the byf FP is unusual but probably good considering the TG and balance of the rifle. No reason to suspect it really...
I am glad to add this combination to my trends too, over time this pattern may prove more common.
