Is the trigger upgrade worth it?
They sent me two left-side safeties instead of a right and left pair, so when they fixed it they included the trigger spring kit. Still sitting in it's bag since the trigger seems fine as-is.
But if it's easy to install and makes a noticeable difference, maybe I will give it a try.
I didnt terribly mind the stock trigger, but it's such a cheap fix - and I havent read anything negative about the HBI components that I just went ahead and did it.
After installation (with the flat trigger from them too), its a very different feeling trigger. I'd say very improved. Taking it to the range tomorrow night for a few hundred rds to ensure functionality.
