Sketchup file was created by me from this particular sample, an original (?) No. 5 Enfield Jungle Carbine flash hider:

This hider is intended to fit over a 0.590 inch outer diameter barrel as found on the real Jungle Carbine, NOT the converted No. 4 repros which have a 0.670 inch outer diameter barrel.  I cannot guarantee that the dimensions will fit your Jungle Carbine.

The CAD file requires requires Sketchup to view.
