Rock River 2 Stage Trigger Job (AR0120NM)

I splurged a little on my first AR build and paid $130 for a lower receiver kit with a 2 stage trigger.  What I didn’t know is that the receiver kit came with a 5 pound trigger.  As I don’t plan to run around with my AR loaded, I might as well make the trigger lighter.  Though the trigger job was so stupidly simple that I don’t know if it deserves to be called a trigger job at all.


Again my little box of $4.5 assorted springs came in handy!  So I’ve effectively spent $4 for two trigger jobs now.


Within the trigger group, the only thing we need to do is to replace this one spring.


The original spring, 0.62mm thick, was replaced with a 0.4mm spring.  Have to cut the spring down in size.  At this point you can leave the spring longer for a slightly higher weight.


Polished out the contacting parts while at it.


Slap everything together, and whoa la!  The trigger is now at 2 pounds.  It might be too light, but it’s pretty easy to switch to a longer spring if need be.
