"How do I install this in my fusion engine

"10/10 fantastic trigger. I am using with my Inferno Spartan and it works great. I have it tuned to the smallest trigger pull!!! it is so light and you hardly have to pull. can just not adjust the set screws and leave it stock if you want a cool trigger with a long pull, but who wants that?

I did find that the set screws kept backing out each game so i did have to use some locktight blue.

would totally suggest this trigger.
