Rock River NM trigger fit?

Fits AR-15 receivers with .154" hammer/trigger pins only. Per package insert
Unless your lower is a Colt large hole it should work. Everybody but Colt is working off the same specs.

Installed my RRA NM Trigger group. Here is how I describe the trigger break: :D Can't say anything else. On a side note the pins went in relatively easy for being "oversized". I pushed them in with my fingers but it takes a punch and hammer to push them back out. Don't know if that is normal.
 
The pins that came with my RRA NM trigger were a lot tighter than the OP describes. Had to use a punch. That's on a Bushy lower. I'm also using the JP fire control group, which I like a lot better than the RRA NM.
 
On the JP "oversize" pins they do mean oversize. I just measured a set of RRA pins and a set out of a JP trigger, .001" diff with the + going to JP. The RRA are .001" larger than the pins in a RRA standard LPK I have.
