Hi, not sure at the moment, tempted to bead blast and anodise black.
Cheers, Nik.

Just a quick update.
Went to my local range yesterday, riffle is super quiet now, but shot 6" of to the right.
Shot about 3 mags and then had a look at the silencer.
Noticed a Silver gray line on the exit hole in the end cap.
I did drill the hole with a 0.5mm clearance for the pellet.
So on returning home I opened the hole by another 1mm.
Bingo, back to shooting on zero.
Just got to strip it down now ready for anodising.
Cheers Nik.

Do you find any difference in amount of sound with a larger hole? Just that I'm using '.22' silencers on .177 & find that they seem to be a little louder than when on .22 guns (or would that be just me?)

Hi Suffolk rifle, I am not sure, I have always assume the tighter the hole the better. But if the internals work really well the hole size (provided its not massive) probably won't make much difference. Baffles etc cut the air around the pellet as it travels, this cutting can affect the path of the pellet if not central, I bet there is a massive equation behind a silencer that some nerd would understand, beyond me, so I try to use a bit of common sense, doesn't always work though.
Cheers, Nik.

All finished and fitted, will try to get some sound meter readings to see how well it works.
Cheers, Nik.

I've got internal spacers made up for a plastic jobbie (very light weight), but haven't yet got round to finishing it - hopefully get some time 'in the shed' soon though

Hi, let us know how you get on, one tip I can give is make sure you keep every thing as central as possible. One thing I noticed was the thread and shoulder where it fits to the barrel needs to be perfect, this will have a massive effect on how tight you can have all your holes. Good luck
Cheers, Nik.

Another morning at the range shooting spot on zero again,
Took if off a couple of times and replaced, just to make sure the zero repeats, spot on.
Cheers, Nik.
