Lenzie were 33-19 winners over Cumbernauld in a tough and competitive BT West Division match at Viewfield on Saturday.
The visitors scored first when Grant Cowie crashed over for a try converted by Andrew Reid, but Lenzie responded well. Scouller scored in the corner, quickly followed by a great burst by Haddow to release speedster Buick.
A conversion put Lenzie 12-7 up but a stunning 70-yard run and try by Andy Thompson squared the match 12-12 at the break.
Another Scouller score, converted by MacKay, was followed by the all important fourth try when David Nisbet evaded the visitors defence from a scrum, MacKay converting.
A well taken converted Zak Davies try cut the gap for Cumbernauld before a David McCrae try in the corner and another Mackay conversion completed the scoring.
This week Lenzie are at home to Cumnock.
