On the set for this price is "adequate", but at least in my case, adjust the essays which are designated for 22er not in a 22er running. With the larger calibers everything fits, but unfortunately just barely and with a careful but notable pressure behind it. The wool and brush heads, however, are made of flexible metal, which one has to bend it all again at what is mentioned pressure after cleaning. This is obviously suboptimal but bearable for the price.
It is very unfortunate that the cleaning staff is by some customs then unceremoniously broken the thread. Hardly combined matching (non-matching at 22ern) essays and a delicate cleaning rod, resulting in this case, in principle usable, but unfortunately in my case, inadequate care set.
