Yes the trigger is fully adjustable and we did have some issues with Cols trigger being to light (for customs or some other "costumed" official, when it left here so we simply swapped out the trigger spring for another. In future any rifles that get shipped to OZ will have the heavier spring fitted which can be easily replaced after import. The standard spring will normally let off at 2.5- 3 lbs which is perfect for most people.
I think the heavy spring will be around 5-8lbs?, haven't checked it on a scale, as its way too much for me, but will pass customs test. Does anyone know what the requiresments are regarding Aussie rules?
Thanks
