I'm redoing a CVA hawken kit gun for my grandson-had a spring drop out when son in law was removing the lock, and,of course the double set triggers dont work right now[really heavy] also acts like the triggers aren't returning properly. Spring is curved,about an inch long, a loop at one end,and a half loop at the other. Made of aprox .015 thick steel- Can't do pic's,except w/cellph. these were discontinued awhile back,factory is no help. Anybody got advice,or know how to get an assembly diagram?
