Replacing factory trigger in bushmaster M4

I ordered a timney 3lb trigger to replace the factory trigger on my bushmaster I bought the day after the election. Not a minute too soon. Anyway the gun is incredibly accurate but the trigger stinks. Does Anyone know if Bushmasters are still using small pins for the assembly or are they the large pins? The trigger is on back order so I can cancel the order if they are the large pins.
