oh sweet man. ive been planning on making a couple like that myself. is that cut from sintra board? my girlfriend has a ton of the stuff where she works and i have a couple pieces ready to shape. how exactly do you shape it? i was thinking of clamping a piece between the breech and tube then dropping it in hot water so it forms itself to the curvatures of the parts

I did a post a few weeks ago similar to this. And I really did boil the breech and riser blank before
clamping them to a 3/4" steel blank to shape the riser. It works very well.

Below is a link to a post that still has some of the
photos. One thing missing in that post was the fact that I used schedule 80 pvc which gives enough
rise for at least a 3/4' shroud and you could probably go 7/8". I wound up sanding down the original
barrel band to a stub that just almost touches the new shroud so essentialy the barrel is floated
inside the shroud.

The shroud is held only by a good fit onto the breech which has been cut to accept the inside diameter of the
shroud. The only clamp involved was the c clamp that pressed everything together while hot, leaving the nice
raised areas where the cutouts go.
I may epoxy the shroud later but so far it hasn't moved at all.
