MMR Tactical - large or small trigger pins?

I'm wanting to swap out the trigger for a drop in - from what I can tell, the MMR tactical uses small .154-inch-diameter pins, can anyone confirm this is accurate?

Thanks
 
@oli700 , is correct.

Colt started using the larger .170 diameter pin holes in their Sporter Match and Match Target commercial lines in the early 90's. All other manufacturers use the mil-spec .155 diameter holes. Even Colt has switched to the smaller mil-spec diameter in recent years...
