Well, what I didn't mention was that this is the first NFA and first supressor/supressed weapon I've purchased so I can't say for sure. Looking at the business end of the weapon, it looks like there are two opposing holes that look to be for a spanner/pin wrench to remove the end off of the supressor so my guess is that it is removable and thusly cleanable.
I've heard through various sources (that are more or less internet trolls) that John's Guns makes a fine weapon. The only other I've seen like this are the integrally supressed Gemtech Oasis (that is no longer offered) and the Amphibian made by AWC. That's all I know.
A little conversation never hurt anyone and that's all I'm really after
