A quick pictorial showing my method of installing an adjustable comb mechanism on a Beretta DT10.
There are many ways of doing it, this is just my preferred method.

Firstly, a paper template is made and taped to the stock. The comb is cut using a deep coping saw and the saw marks sanded flat using a block to ensure nice crisp edges. The mechanism is then centered in the cut out and carefully marked with a knife.

Due to it's awkward shape, a router can't really be used to inlay the mechanism, so drill bits and chisels are used instead. Smoke on the metalwork shows where the high spots are, meaning a snug fit can be achieved. Once inlaid, two pins are hammered in to the centre of the nuts and nipped off just proud. The comb is then pressed in place, revealing two reference marks for drilling the sleeves.

The sleeves are drilled and glued in to place. Grub screw holes are carefully marked and drilled. A block and wedges are used to make sure everything is square. Once drilled, they are tapped with a 10-24 thread.

The raw areas are then carefully sprayed to match the original finish and the gun is reassembled.
