no parts available other than springs (aftermarket)...at least as far as I know...Shanghai has stopped shipping parts from what I have been told...
Seems there are two versions of the QB36. The -2 has a longer stock like the TF99 and the -1 has a shorter stock and barrel.Also there is the TF97, about the same gun as the TF99 and a TF87 that has the bear trap release lever in front of the trigger and safety levers inside the trigger guard. The 99, 97 and 36 the bear trap release lever is behind the trigger. Something like that kinda' sorta'.Awhile back I found an old 97 cheap parts gun missing the front sight/cocking lever holder, the rear sight trigger guard and recoil pad but it would shoot. I got it and put a B3 barrel clip and steel muzzle break on it and a rubber slip over recoil pad and fabricated a trigger guard from an old Peak B4 under lever. They're big trgger guards. Scoped it and it shot pretty good. There's another in similar condition on Ebay now.
