I recently purchased a DPMS 308 Mk12 rifle.  It comes with an adjustable JP single stage trigger.  I'm not a huge fan of this trigger and want to swap it out with a 2 stage.  I have a CMMG 2 stage unit that I purchased a while back for a build - subsequently put it away and forgot I had it until I "found" it this weekend.  I am wondering if this is a good way to go for this rifle set up.  I have read that many parts are interchangeable but I have no first hand experience since this DPMS is my first 308 AR.
Thanks in advance for you comments.

That trigger should work. It is on the same platform. I believe all the FCG will interchange to the best of my memory.
