Ar 15 small pin 3 lb trigger - Timney Triggers AR-15 Competition Trigger

Have purchased other Timney Triggers and been quite pleased. Not so with this one. Installed very easy but that is about the end of the pleasant experience. Bought a 3 lb trigger, received a 4lb 12 oz one. Called Timney Tech Support twice, could not get a person, had to leave a callback message. Still have not had a callback. I worked on this trigger myself and now have it down to about 3 1/2 pounds without touching any adjustments. It is better than the stock one but not as good as the Geissele I purchased for my other ar. I would not recommend this Timney trigger for an ar based on my experience, buy the Geissele.
