Rock River 2 Stage Trigger in Norc M4?

[Ganderite]

I shot my new Norc M4 today in a CQB match. lots of fun and rifle never missed a beat. I melted in the heat and grew some extra thumbs...

The biggest mistake I made, by far, was dry firing a rifle with a Rock River 2 stage trigger. This makes the rifle a real rifle! I could actually aim at a target and hit it with that kind of trigger.

But, when i did some Internet searching, I found this warning:

" Fits Standard (NOT COLT) AR-15 receivers with .154" hammer/trigger pins only (Like DPMS, RRA, Armalite, Olympic."

Would this trigger fit the Norc?

I swapped out the Norc trigger group & hammer with GI parts over a yr ago
Difference was night & day

Got mine from Questar. Drops in like a charm and works nice.

Brownels also has them.

The RRA 2 stage is not that great at all, its cheap but thats about it. Try a Geiselle DMR or Timiney one piece ( my favourite )and you will say the same thing about the RRA as you are saying about the factory Norc crappy trigger.
They really are night and day.

Tim suggested I just measure the pins. Duh!

So I pushed one out a little bit and put the vernier on it. 0.156"

Guess that is the right size for the Rock River.
