I just my stamp for my form 1 quell tech mod-u-less. I took it to the range today and it just sucks. It shot 4 mils low and 4 mils left from my normal poi. It also wouldnt group for shit either. I am stumpped why this is doing this. My other form 1 can shoots great.
the group on the upper right is my quite bore can and the group on the lower left is my quell tech.
