    Not for everyone

    This trigger is a mixed bag for me. I figured I'd try one out due to rave reviews online, but overall wish I'd gotten a different one. I don't like the takeup being heavier than the break or the flat trigger face. It turns out that I prefer a curved trigger and I'd definitely prefer a lighter 1st stage.

    The trigger does have a crisp break though and is 100% reliable. It is also an easy install.

    Well worth it.

    I have put this trigger in two guns so far, and it has been worth every penny. They were both easy to install (less than 10 minutes from start to finish), and are a majhor improvement on the factory units. Pull weights are consistent, without variation, which I tested by averaging the pull weights over 20 shots each. If you are still using the factory trigger on your AR, save your money and get yourself a Geissele; you won't be disappointed.
