30% failure to fire with IMI M193 and M855 doesn't sound like mountains out of mole hills to me.Hmpffff.
Mine works like a charm, no problems at all. Boss Hogg sent me a spare spring just in case but I can't be bothered with it. The Timney is a good trigger. Boss Hogg is a good supplier. This is an extremely minor problem that I think is being blown out of proportion. If you have any problems the boys have stated over and over again that they will make it right. Worst case is you use the old trigger group until the new one gets sorted out. Mountains are being made of mole hills.
