Info for vt3 compact x16 came directly from sales stand in the British shooting show in Birmingham England, when I tried to buy another VT3 compact which was out of stock, I was advised to wait as the x16 was shortly coming out.
I am a true lefty, and shoot a wildcat with a left hand cheek piece very comfortable, also there are a few MK1 left handed Wildcats kicking about if you can find one.
