Straight foward to clean but yes you are correct it does not have a hooked breech. I have never taken the barrel out. Just swab with wet patches, pour a jug of boiling water down the barrel, more patches, last one with CRC 5.56 on it. Remove the lock and clean/oil it , pretty much job done.
I picked my one up for about half what they are selling for new now a few years back, the previous owner had bought it shot it but it wasn`t his thing so it was like new when it arrived with me. Would I buy it again, Yes but not at what they now want for them, I`d look for a 2nd hand T/C.
