Hi RiffRaff,
Your post got me thinking today about my SAK silencer that i use on my R10.
I took in apart to find only 1 piece inside it, so thought that i would try abit of your idea to see if i can improve on it any.
I used some kitchen cleaner and cut it to size, then rapped it in celetape to hold it firmly in place before putting the outer cover back on.
When i fired it WOW the difference was amazing pal, so its staying on from now on.
Cheers Budddy for the idea
Si
