well so far there are none ... we had a member try and use SLK320 ones and it did not work out ...

you have a set made that can fit either SRT-6 or regular i am sure you will see plenty of people on it ... i am interested to see them made as well, would love a long tube design, stainless of course ... would definitely something i would buy, price would dictate how soon only, not if ... quality would dictate if i would buy them ...
