Well, after fire-lapping my AR1000's barrel with valve grinding paste (and ruining it), and after several abortive attempts at drilling out the barrel so I could install a liner, and after having Beeman (same gun as the SS1000), Compasseco (same gun as the TF89), Air Gun Inc, and the factory in China tell me "NO DICE!" on getting a new barrel...
I managed to fit an old Shadow .177 barrel to it.
So how is it now?
Well, I've got a largish rifle with a long pull and a hefty cocking weight that does 920-930 with CPL's despite it's large powerplant. Don't know what's up with that, used to do over 1000, could be a relaxing spring (is it just me, or do Industry guns have a problem with that?) or something else, or maybe it's something to do with the barrel.
At least it groups OK, although it is harder to shoot well than a Gamo...
Learned a lesson - finally, I think - no parts, no service, no sale!
