Mine came with the super ACR trigger. It is definitely nicer than my buddy's stock trigger pull but I don't know if it's $300 nicer. I doubt I would have paid for it if the rifle didn't come with it.
What's fireclean? I can't tell a difference between how mine cycles from the video.
How much does the Geissele trigger pull weigh? I'd love to try one to compare.
FIREClean is a lube. The action feels like it is riding on ball bearings. Did the same to a 1911. I will apply it on my m&p 9 when it shows up and I will run a few hundred rounds to see.
