The height of the smallest Sightmark LoPro is 1.4". The VCOG center optical axis is at 1.535". Subtracting half the objective lens diameter (12mm), the bottom of the objective lens is 1.065"above the rail, meaning the Sightmark laser would impede about 0.34" of the objective lens.
What you could possibly do is offset the laser at the 3 or 9 o'clock position on the rail to keep the 12 o'clock position clear for the scope.
