I think if you want to make the end round out, you can use some kind of epoxy putty and shape it by shaving off excess till you get the desired shape. IMO with the low prices of chinese made parts, this DIY project is pretty much pointless unless your government prohibits import of toy silencers. Or unless you want a custom length/thickness.

It does look quite shoddy to me too so I'm not offended.
The "closed up" is due to the fact that I had no idea epoxy putty existed at the time. Looking back I could have done a better job. I epoxy steel or JB weld so the viscosity didn't allow for me to shape it to a rounded end that Dozer was able to achieve. I have tried quite a few times to refine it. But I've pretty much lost patience after gaming season started :P

I'd love to help you but I've sold off those MP5s and the silencers are gone too :{(

Cheers and good luck to your endevour!
