Hmmm I am wondering how often, i.e how many rounds fired, do you think before the moderator should be stripped and cleaned. Have looked on their website and although it tells you how to clean it no mention is made of the frequency.
Now I stripped mine last night and had a bit of trouble unscrewing the calibre adaptor and blast shield due to the carbon build up so it was obviously due for a cleaning . This time I just used hot Soapy water as suggested but there is some more stubborn burnt on carbon so perhaps I had better get some brake cleaner as it suggests. I used a pan scourer to clean the Stainless steel blast shield so now I have to get out a new pan scourer before Mother notices but it's shiney again .
