So I was doing the Devils lair about a week or so ago and I fired an ordinary scout rifle round at the walker and it did 5000 damage, not really sure if it was some kind of glitch or an actual weak point but I haven't been able to do it again since I'm hoping someone is able to shed some light on why this happened

It's possible, I'm sure my brother said he his the crit spot on it for 26k whilst doing nightfall, he was using Ice Breaker. And I've hit Vex Goblins in crit spot for 15k the week before again using Ice Breaker
