Forends are much harder to do, as a rule, because they have more surface area to fit against, multiple areas of inletting for hardware and nice ones get very thin by the time you are done. Real easy to make a 2X4 club end, very hard to make a trim, thin very well shaped fore end sometimes.
The release on this one has to be fit correctly. If you make it too short it will lock the fore end on the gun and will require the gentle use of a chisel to split the fore end. Then you get to start over again. Happy days, this event is, to put it mildly.
I would have your current forend copied and use that as a basis to make the splinter. Any of the duplicators can do this and the money invested will be well spent.
