Sill working on my DVH; found some perfect cheap len's for E11 scopes on Amazon. About 3 or 4 bucks each! These are the sizes I got, but I may get one size up for the larger len s.
Simply drimmel the outer ring holding the len's first and then pry the metal apart, the len's will fall out. Drill or drimmel out your scope ends to hollow them out, and your done! My blaster is all dusty from the drilling and still all taped up for glueing, but I will show finished picks on my build thread. I wont glue these in until after the blaster clean up and painting.
