Any Tips for Firing Burst Fire Weapons like the M4 or M16A4? There is always a b

Hey, so i wanted to ask for tips around the burst fire weapons incl. M4 and M16A4; the burst fire rate stutters/halts at points when you fire. Ive tried matching my RT / trigger pulling to the tempo of each burst - it doesnt do the full thing, reliably (of shooting the full magazine at the same rate of fire).

if you just mash RT like normal, then what i find is sometimes it halts like 12 bullets in.

i basically want uninterrupted, full spray control with these weapons and i've been unable to master a technique to get that!! i even have been using brand new controllers recently.
i'll have to try at the game shooting range to figure it out further.
