I'm sure they will... and soon. I have an F1 now, but it's on a hunting rifle.Maybe at some point, NF will come out with an SHV F1 with more top end magnification than 14x. 1000yds can be be done on 14x for sure, but for dot drills smaller targets, more precise shooting, it would be nice to turn it up a bit.
Thing is, I'm not sure if the extra magnification on an F1 would do you any good. On the 4x14 the reticle fills the scope at 14. Any more magnification and it will be cutting off that higher value holdovers.
