My father just acquired a QB25 made by Techforce. He hasn't done anything to it yet but wipe some of the gunk out of it. Is anyone familiar with the disassembly of this rifle. He says it has a knurled cap on the end of the tube and two pins forward. He does have a nice spring compressor and a mill and a lathe, so he is mechanically able to make parts, just not familiar with this design. He is somehow getting 15yard cloverleaf groups out of this thing and he says his barrel isn't locking up solid either. If anybody wants to chime in on this one, we're all ears. I'm trying to talk him in to becoming a member. I know you'll read this Dad, so just become a member, these guys and gals are very helpful.
Thanks
